// Create a new button that says 'Info'
const infoBtn = document.createElement('button');
infoBtn.classList.add('btn', 'btn-primary', 'px-5');
infoBtn.innerText = 'Info';
// Create a new button that says 'Cancel'

cancelBtn.innerText = 'Cancel';
// Place the 'Info' button before the original button
button.before(infoBtn);
// Place the 'Cancel' button after the original button

// Just for fun, let's imagine these buttons in action
console.log("The Info button is like the appetizer, it comes before the main course!");
console.log("The Cancel button is like dessert, it comes after everything else is done!");
```
In this version, the before and after methods are used with a humorous analogy, comparing the placement of the buttons to courses in a meal:
The **infoBtn** (Info button) is placed before the original button, likened to an **appetizer**.
The **cancelBtn** (Cancel button) is placed after the original button, likened to **dessert**.
This adds a fun and relatable context to understanding how the buttons are positioned in relation to the original button. | __khojiakbar__ | |

We also hooked up a Rails app to AppSignal, seeing how simple errors are tracked and displayed in AppSignal's Errors dashboard.
In this part of the series, we'll dive into how to set up the following for your Ruby on Rails application using AppSignal:
- Performance monitoring
- Rails background jobs monitoring, including how to monitor simple API calls
- Logging
- Notification alerts
Let's get into it!
## Monitoring Rails App Performance Using AppSignal
When your uptime monitor shows that your app is up, it may be tempting to think that everything is okay. But, in reality, trouble could be brewing under the hood in the form of slow processes, unoptimized database queries, and long-running service calls.
This is a very important matter when you consider that there's a [correlation between slow-loading web pages and a low visitor conversion rate](https://www.thinkwithgoogle.com/marketing-strategies/app-and-mobile/mobile-page-speed-conversion-data/). In a nutshell, those slow-running processes will cost you a lot if left unchecked. But with so many moving parts to a Ruby on Rails app, the important questions are: what should you look for, and where?
That's where AppSignal comes into play. Let's look at how you can use AppSignal to keep track of your Rails app's performance.
### Tracking Response Times
From the default dashboard, AppSignal provides two graphs that can give you a quick overview of how slow (or fast) your Rails app is running: the _Throughput_ and _Response time_ graphs.
- **Throughput** - This basically measures how many requests per second your app is currently processing (not to be confused with how many requests per second your app can handle overall). The basic rule of thumb is: the more requests per second, the better. However, if your app server handles too many requests per second, it might be time to scale your server resources to handle this.
- **Response time** - The average time a browser response takes in milliseconds. The more time a response takes, the worse your app is running. A good rule of thumb here is that if your Rails web app has sub-100ms response times, you can consider it fast, while 300ms+ response times can be considered slow.
Now, let's say we want to track our app's response times and throughput over a seven-day window. That's very easy to do — just go to the _Graphs_ sub-menu under _Performance_ located on the left-side menu, then use the time filter buttons on top of the graphs, as shown below:
With that, you can easily see if your app runs slow on some days compared to others.
While on this view, it's also important to check out the _Event groups_ graph, located below the _Response time_ and _Throughput_ graphs:
This graph gives you details on how fast or slow your app is running in the controller layer and the view layer. From here, you can find out what's causing slow response times and fix the issues accordingly.
Let's now switch gears to tracking database queries using AppSignal.
### Tracking Database Queries
It is generally true that you can squeeze a lot more speed from your app by optimizing response times and throughput. However, more often than not, slow, unoptimized database queries are the worst offenders when it comes to sluggish app behavior.
Let's take an example of the infamous N+1 query. In the [expense tracker app](https://github.com/iamaestimo/expense-tracker) introduced in part 1, the index method in the expenses controller looks like this:
```ruby
# app/controller/expenses_controller.rb
class ExpensesController < ApplicationController
...
def index
@expenses = Expense.all
end
...
end
```
This might look innocent, but if you take a look at the _Issues_ list in your AppSignal dashboard, you'll see something interesting:
An N+1 query has been highlighted in the expenses controller's index method.
If we dig further by clicking on the issue link, we get to an _Issue details_ screen like this:
Notice how AppSignal offers an explanation of the issue, including a link to a more detailed blog post showing you how to deal with it.
Let's move on and learn how AppSignal helps you out with background jobs.
### Keeping Track of Rails Background Jobs with AppSignal
Background jobs are a common feature in many production Ruby on Rails applications, with a variety of job queue processing gems and libraries for you to choose from.
AppSignal supports tracking and monitoring various background job processing libraries, including Sidekiq, Que, Delayed Job, Resque, and others.
Let's say we want a feature where users get daily currency exchange rates in their dashboard.
For this to work, we need an API call to a service providing such rates (we'll use one that doesn't require too much upfront configuration or payment, like [this one](https://www.exchangerate-api.com/docs/free), to fetch currency rates). We also need a background job to queue the call to this service at regular intervals.
The background processing gem we'll use in the expense tracker app is [GoodJob](https://github.com/bensheldon/good_job), but you're free to use whatever suits you.
Let's create a background job to fetch rates:
```ruby
# app/jobs/fetch_rates.rb
...
class FetchRates < ApplicationJob
self.queue_adapter = :good_job
def perform
# fetch rates
response = HTTParty.get('https://open.er-api.com/v6/latest/USD')
if response['result'] == "success"
Rate.create(
base_rate_name: response['base_code'],
eur: response['rates']['EUR'],
cad: response['rates']['CAD'],
aud: response['rates']['AUD'],
gbp: response['rates']['GBP']
)
end
end
end
```
And then set GoodJob to run a cron for this job every few minutes (or however you see fit). AppSignal automatically detects the presence of the background service and includes a nifty filter so you can separate it from the default web dashboards:
Without the need for much tooling upfront, AppSignal will also detect API calls and keep track of any issues:
If you want to dive deeper into monitoring Rails background jobs with AppSignal, I recommend you [check out the documentation](https://docs.appsignal.com/ruby/integrations/active-job.html). For now, let's turn our attention to uptime monitoring.
## Uptime Monitoring
Another matter that concerns many Rails developers is the continuous availability of their application for end users. Any downtime might mean loss of revenue and have other negative consequences.
Even so, you wouldn't want to poll the uptime status of your app manually. You can set up uptime monitoring using AppSignal.
Setting it up is a breeze. Begin by clicking on the _Uptime monitoring_ link in the left-side menu.
Then, when you click on the _create uptime monitor_ button, you should get a dialog similar to the one shown below:
Complete your uptime monitor by adding the most important settings:
- **Name** - Give your uptime monitor an appropriate name.
- **URL** - Provide the full URL to the uptime route. Beginning with Rails 7.1, the default uptime route is _https://your-app-domain/up_.
- **Region** - Select the regions where you want to check for uptime.
- **Notification** - Choose the notification channel/s to receive alerts on.
With that done, go ahead and create the monitor!
One thing to note with the AppSignal uptime monitor is that since polling is done almost every minute or so, it's very easy to hit your plan's limits. But there's a very good workaround to this which you can read more about [in their docs](https://docs.appsignal.com/uptime-monitoring/setup.html).
Before moving on to how AppSignal can help with logging, there's another important feature to complete the uptime monitoring layer: free [public status pages](https://docs.appsignal.com/uptime-monitoring/public-status-page.html#set-up).
Click on the _creating a public status_ page link as shown below:
Then click on the _New status page_ button, bringing you to this:
Go ahead and fill in all the required information. Note that if you use a custom domain, you'll need to add a CNAME directive pointing to `cname.appsignal-status.com` in your custom domain's DNS settings.
## Logging with AppSignal
Logging is a relatively new feature in AppSignal, but one that is timely and welcome. Using AppSignal, you don't have to run application monitoring and logging as separate services.
To get started with logging, make sure you are running the latest version of the AppSignal gem. If you have an older version of the gem, update it with:
```shell
bundle update appsignal
```
Then create a new initializer and edit it like so:
```ruby
# config/initializers/appsignal_logging.rb
appsignal_logger = Appsignal::Logger.new("rails")
Rails.logger.broadcast_to(appsignal_logger)
```
Now you can access your app's logs like so:
Notice that you also get a nice filter to filter log records by severity, as well as access to live logs.
You can go through [AppSignal's logging for Ruby documentation here](https://docs.appsignal.com/logging/platforms/integrations/ruby.html).
## Other Notable Features
There are a couple of other notable features you can use in AppSignal: anomaly detection and custom metrics.
### Anomaly Detection
Let's say you are concerned with your app running out of memory. You can easily set up a trigger that sends an email notification if your app has a notable drop in available memory.
Go to the _Anomaly detection_ link and create a new trigger, then configure it:
- **Metric** - In my case, I am interested in memory usage, but you could choose any other metric that is specific to your use case.
- **Trigger details** - Here, you'll configure the details relevant to your trigger. In my case, the trigger will fire if the host memory goes below 200MB.
### Custom Metrics
AppSignal also gives you the tools to capture and visualize custom metrics. This feature alone warrants an entire article. You can read all about it in [How to Monitor Custom Metrics with AppSignal](https://blog.appsignal.com/2023/04/26/how-to-monitor-custom-metrics-with-appsignal.html) and [check out AppSignal's docs](https://docs.appsignal.com/metrics/custom.html) too.
## Wrapping Up
In part one of this article series, we set up a Rails app hosted on DigitalOcean and monitored it for errors using AppSignal.
In this second and final part, we looked at some of AppSignal's great features for your Rails app, including performance monitoring, uptime monitoring, logging, and more.
There's so much more to AppSignal than could effectively be covered by this article series. I highly encourage you to check it out for your Rails app.
Happy coding!

## Accountability: Taking Responsibility
**Definition:** Accountability involves taking responsibility for the software developed and its impact on users and society. It means being answerable for actions and decisions, and taking corrective measures when necessary.
**Importance:** Accountability ensures that developers and organizations are held responsible for their software, fostering trust and ensuring that issues are addressed promptly and effectively.
**Best Practices:**
- **Reporting Channels:** Establish clear channels for users to report issues and concerns. Ensure these reports are addressed promptly and transparently.
- **Transparency About Errors:** Be open about errors and breaches. Communicate what happened, the impact, and the steps taken to rectify the situation.
- **Documentation and Logs:** Maintain detailed documentation and logs for auditing and compliance purposes. This helps in tracking actions and decisions.
**Examples:**
- **Facebook’s Bug Bounty Program:** Encourages external researchers to report vulnerabilities. Facebook takes accountability by addressing these reports and rewarding researchers for their contributions.
- **GitHub’s Transparency Reports:** GitHub regularly publishes reports on government requests and actions taken on the platform, demonstrating accountability and transparency.
Understanding and implementing these core principles of ethical software development is essential for creating software that is respectful, fair, secure, and accountable. By adhering to these principles, developers can ensure their software not only meets technical requirements but also contributes positively to society. In the next article, we will explore practical steps and considerations for integrating these ethical principles into the software development lifecycle. Stay tuned as we continue this journey towards more ethical and responsible software development.

1,901,263 | Amazon Brand Registry: Merits and Demerits | Amazon Brand Registry is a program designed to help brand owners protect their registered trademarks... | 0 | 2024-06-26T11:59:00 | https://dev.to/adambrooks2223955/amazon-brand-registry-merits-and-demerits-2a9d | amazonbrandregistry, amazonbrands, amazonbrand | Amazon Brand Registry is a program designed to help brand owners protect their registered trademarks on Amazon and create an accurate and trusted experience for customers. Since its launch, the program has evolved significantly, offering a range of tools and benefits. However, like any program, it also comes with its challenges. This article will explore the merits and demerits of the Amazon Brand Registry in detail.
**Merits of Amazon Brand Registry
**1. Enhanced Brand Protection
One of the primary benefits of enrolling in the Amazon Brand Registry is the enhanced brand protection it offers. The program helps brand owners protect their intellectual property and product content on Amazon, ensuring that customers receive authentic products. The tools provided include automated protections that use information about your brand to proactively remove suspected infringing or inaccurate content.
**2. Improved Control Over Product Listings
**Brand owners gain more control over their product listings. They can manage product detail pages to ensure that the information provided is accurate and up-to-date. This control extends to product titles, descriptions, images, and other key attributes, reducing the chances of incorrect or misleading information appearing on their listings.
**3. Access to Advanced Search Tools
**The Brand Registry offers powerful search and reporting tools. These tools allow brand owners to search for content in different Amazon stores and report suspected violations. The search tools include features like image search, bulk ASIN search, and global search capabilities, making it easier to identify and act against potential infringements.
**4. Brand Dashboard
**The Brand Dashboard is a centralized location where brand owners can access various tools and reports. This dashboard provides insights into the performance of their brand on Amazon, including brand analytics, customer reviews, and brand health reports. This data can help brands make informed decisions about their strategies and operations on Amazon.
**5. Enhanced Brand Content (EBC) and A+ Content
**Amazon Brand Registry members can use Enhanced Brand Content (EBC) and[ A+ Content](https://www.sellerapp.com/blog/amazon-a-plus-content/) to improve their product listings. These tools allow brands to create more engaging and informative product pages with enhanced images, videos, and detailed descriptions. This can lead to higher conversion rates and increased sales.
**6. Sponsored Brand Ads
**Registered brands can access Amazon’s advertising tools, including Sponsored Brand Ads. These ads allow brands to promote their products more effectively on Amazon, increasing visibility and driving more traffic to their listings. Sponsored Brand Ads can appear in prominent locations, such as the top of search results, making them a powerful tool for brand promotion.
**7. Amazon Brand Analytics
**Brand owners gain access to Amazon Brand Analytics, which provides valuable insights into customer behavior, including search term reports, demographic data, and market basket analysis. These insights can help brands understand their customers better and refine their marketing strategies to improve performance.
**Demerits of Amazon Brand Registry
**1. Eligibility Requirements
One of the significant challenges of the Amazon Brand Registry is its eligibility requirements. To enroll, brands must have a registered trademark in each country where they wish to enroll. Obtaining a trademark can be a lengthy and expensive process, which may be a barrier for smaller or newer brands.
**2. Complexity and Learning Curve
**Navigating the Amazon Brand Registry and fully utilizing its tools can be complex, especially for those who are new to the platform. The learning curve can be steep, requiring time and effort to understand and effectively use all the available features. This complexity may deter some brands from fully leveraging the program’s benefits.
**3. Enforcement Challenges
**While the Brand Registry offers tools for reporting and removing infringing content, the enforcement process can sometimes be slow or ineffective. Brand owners may find that their reports are not always acted upon promptly, and infringing listings can reappear even after being removed. This can be frustrating and may require ongoing monitoring and reporting.
**4. Cost Implications
**There are indirect costs associated with the Amazon Brand Registry. While enrollment itself is free, obtaining the necessary trademarks involves legal and registration fees. Additionally, creating high-quality Enhanced Brand Content and running Sponsored Brand Ads requires investment. These costs can add up, particularly for smaller brands with limited budgets.
**5. Dependence on Amazon’s Ecosystem
**Enrolling in the Amazon Brand Registry ties a brand more closely to Amazon’s ecosystem. While this can provide significant benefits, it also means that brands are more dependent on Amazon’s policies and changes. Any changes in Amazon’s algorithms, policies, or fees can directly impact the brand’s performance and profitability.
**6. Limited to Amazon
**The protections and benefits of the Amazon Brand Registry are limited to the Amazon platform. While this can be sufficient for brands that primarily sell on Amazon, those with a broader e-commerce presence may need to invest in additional measures to protect their brand and products on other platforms.
**7. Potential for Abuse
**The tools provided by the Brand Registry can sometimes be misused. There have been instances where brands use the reporting tools to target competitors unfairly. This abuse can lead to unjustified takedowns and disputes, creating challenges for brands trying to operate fairly within the marketplace.
**Conclusion
**The Amazon Brand Registry offers a range of powerful tools and benefits designed to help brand owners protect their intellectual property, improve their product listings, and enhance their presence on Amazon. The enhanced brand protection, control over listings, advanced search tools, brand dashboard, Enhanced Brand Content, Sponsored Brand Ads, and Amazon Brand Analytics can provide significant advantages to enrolled brands.
However, the program also comes with its challenges, including eligibility requirements, complexity, enforcement issues, cost implications, dependence on Amazon’s ecosystem, platform limitations, and potential for abuse. Brands considering enrollment should weigh these merits and demerits carefully to determine if the Amazon Brand Registry aligns with their business goals and capabilities.
Overall, for many brands, particularly those heavily invested in the Amazon marketplace, the benefits of the Brand Registry can outweigh the drawbacks, providing essential tools to protect and grow their brand presence on one of the world’s largest e-commerce platforms.

**Introducción**
Quiero debutar en Dev.to con un artículo sobre una librería que ha sido la culpable de que poco a poco me vaya gustando ese famoso lenguaje de la web, ¡sí! la verdad es que siempre trabajé a regañadientes con JavaScript.
Para resumir que es React, señalemos que es una librería que ayuda a crear interfaces de usuario encapsulando funcionalidad y apariencia en fragmentos de código llamado **componentes**
Hagamos un pequeño ejercicio para conocerlo.
**Requisitos:**
1. [NodeJS](https://nodejs.org/es/)
2. [Visual Studio Code](https://code.visualstudio.com/), o el editor de tu preferencia :).
3. Navegador web, yo te recomiendo [brave] (https://brave.com/?ref=isa648/)
**Objetivo**
La funcionalidad del componente es sencilla. Tiene que presentar "Hola React, soy .... ¡Mucho Gusto! ".
Manos a la obra de arte. :)
**Paso 1**
Crea una carpeta para contener el proyecto, abre una consola y haz uso de [**create-react-app**](https://es.reactjs.org/docs/create-a-new-react-app.html#create-react-app) seguido por el nombre que desees darle.
Esto tomará un par de minutos, aquí debes aprovechar para ir por una cerveza, buscar una buena playlist o solo ir al baño. :)
**Paso 2**
Elimina los archivos de la carpeta **src** exceptuando al mimado **index.js** y **App.js**, en el menú terminal seleccionemos **nuevo terminal** para usar **npm start**. Con esto estarías poniendo en ejecución el proyecto.
Si haz borrado los archivos obtendrás la siguiente pantalla con un error.
**Paso 3**
Antes de depurar mira que contiene index.js.
- *React.* Este paquete es omnipresente. Y entre tantas cosas te ayuda a trabajar con [JSX](https://en.wikipedia.org/wiki/React_(web_framework)#JSX).
- *ReactDOM.* Su principal función es mantener actualizado los elementos de React y del [DOM](https://es.wikipedia.org/wiki/Document_Object_Model).
- *App.* Es el componente que vas convertir en `MyComponent`, el cual implementa la funcionalidad.
**Paso 4**
Renombra el archivo *App.js* a *HelloWorld.js*. Crea un componente mediante una función, esta tendrá el nombre de *MyComponent* y recibirá un objeto como parámetro llamado [**props**](https://www.w3schools.com/REACT/react_props.asp), útil para pasar *datos* como por ejemplo nombre, edad, sexo, etc.
A esta función le acompañaran un import React para poder hacer uso de JSX y un export poder referenciarla en el archivo *index.js*
`props.**name**` es una expresion javascript y como todas debe estar dentro de llaves *{}*
**Paso 5**
Modifica index.js, aquí harás uso de **.render** de ReactDOM para poder dibujar el componente en el navegador, el segundo parámetro que recibe *render* es un elemento html que sirve de contenedor al componente que haz creado, échale un vistazo a **index.html** dentro de la carpeta *public*.
*MyComponent* tiene la capacidad de recibir un dato en una prop llamada *name*, así que es conveniente que la uses.
**npm start** para verlo en acción,si es que ya no lo hiciste en el paso 2.
**Paso 6**
Por último dale color al componente, para ello crea un objeto con todos los estilos que desees aplicar, luego úsalo en la prop [**style**](https://www.w3schools.com/react/react_css.asp).
.
¡Si! le he agregado un elemento html `<div>` para contener al `<p>`, es importante tener en cuenta que una función que crea componentes siempre debe devolver un elemento.
Resultado:
**Fín**
Así que ahí lo tienes, espero que este pequeño post te sirva para darle una oportunidad a React y disimuladamente a JavaScript. :)
¡Gracias por leer!

Whatever ego I entered the training room with that day left my body faster than the beads of sweat puddling below me.
This humbling experience was nearly 15 years ago. It was the first time I did live rounds of submission grappling.
Prior to it I had some experience in traditional wrestling and thought adding in submissions to the equation wouldn’t be all that different.
Ego was my tuition payment on that error.
My Harry Potter-esque training partner was a jiu-jitsu brown belt who was preparing for ADCC trials (the grappling equivalent of the Olympics), and I was a fresh young white belt who thought I was up for the challenge relying on brute force alone.
He quickly dispelled me of this notion by repeatedly submitting with ease.
He had an answer for every attack I attempted.
In fact, the harder I tried to force positions, the easier it seemingly became for him to exploit the massive holes in my game.
It wasn’t until I had an additional year or so of training that I even understood how it happened, but over time I came to realize that day I was playing checkers while my opponent was playing chess.
I think back on that first day of training and the lessons I’ve learned on the mat since because the principles of jiu-jitsu have so many parallels with trading….
The harder you try to force a trade the way I tried to enforce my will on my opponent that day, the worse positions you’ll find yourselves in.
Rather than attempting to jam a square peg through a round hole, you’re better off waiting for the perfect set-up to present itself then executing swiftly when it does.
I bring this up now, because from my perspective the Bitcoin options market isn’t giving us a whole lot of reasons to be active.
What this boring, range bound market does offer us however is the time to study the current structure and share some signals to be on the look-out for which will offer much cleaner set-ups if they come to pass as we exit Q2.
So without further ado let’s dive in….
The Chop Don’t Stop
We had both a CPI print and FOMC announcement last week. And even some decent price action to start the week.
Yet not much has changed on BTC from an options volatility perspective.
As we can visualize on the BVIV implied volatility index chart below, each and every spike in IV since the March highs has been promptly sold off. This has created a long series of lower highs and lower lows on the chart.
This week was no exception as Wednesday morning’s high of 55 quickly reverted -10% back down to 50 by Thursday afternoon.
Volatility crushed.

**Introduction
**
In the digital age, data is compared to the lifeblood of modern business, driving the decision-making of modern business, powerful innovative applications, and fueling the growth of organizations in all sectors. The very heart of this data-driven landscape is the wizardry of database management: a critical discipline that allows the storage, retrieval, and manipulation of information to be done efficiently. This comprehensive course will enable you to know more about the world of database management, which holds some very basic concepts, growing trends, and how worthy it is to integrate database skills along with web development.
**Database Management Understanding Of Main Concepts
**
Database management is a process that includes the development, design, and provision of a database system for creating, updating, and managing data effectively. This area involves a diverse set of activities, starting from defining data structures and relationships to enforcing data integrity, security, and access to the data. The knowledge of core principles related to database management creates the baseline for implementing any data-driven application successfully.
**Relational Database Management Systems (RDBMS)
**
Relational Database Management Systems have been in business for quite a while. Systems like MySQL, PostgreSQL, and ORACLE pack data in a tabular layout with specified relationships that facilitate the retrieval of queried data, allow seamless access and manipulation of huge volumes of data, and manage transactions effectively. Learning these fundamentals of RDBMS, such as schema design, indexing, and query optimization, is imperative for any next database professional.
**Exploring NoSQL Databases
**
RDBMS had been the choice for many applications. The rise of big data and the need for scalable, flexible data storage brought on the NoSQL database systems revolution. Systems such as MongoDB, Cassandra, and Redis are not relational but have some distinct advantages in the aforementioned areas: scalability, performance, and managing of unstructured data. Insight into these strengths with their use cases is very important for developing modern, data-intensive applications.
**Database Design and Normalization
**
Good design of a database is the foundation of good database management and results in the efficient storage of data as well as the ease of retrieval and maintenance of that data. This is an overall process of defining entities, their relationships and the appropriate normalization technique to implement for minimization of data redundancy maintaining data integrity. Database design is another skill that goes hand-in-hand with good database administration and development practice.
**SQL - Structured Query Language
**
SQL is the de facto language for dealing with any relational database: writing complicated queries, managing transactions, and optimizing database performance. Working with a database must become the next skill following SQL syntax mastery and best practices adoption in order to manage databases in a proper way.
**Database Administration and Maintenance
**
Database administration involves many concerns, from security matters and backup procedures to the fine details of performance monitoring and optimization. The best database administrators have a strong technical background, blending system architecture and an understanding of resource management with various means for troubleshooting.
**Integrating Databases with Web Development
**
Databases now are an important competency in the modern web development landscape. Web developers are required to create, develop and maintain web applications that are driven and connected or linked to databases using their skills in technologies such as SQL, Object-Relational Management (ORM) mapping frameworks, and API development. This ability to apply the web-based application of database management and web application development skills is sought after in a good number of industries.
**The Importance of [Web Development Courses ](https://bostoninstituteofanalytics.org/full-stack-web-development/)in Database Management
**
As the demand for data-driven web applications rocketed, the need for professionals who are able to amalgamate web development onto database management became more than compelling. Courses on web development with the principles of management in databases can empower budding developers and aspirants in the IT industry by arming them with the right tools to design, develop, and maintain effective, scalable, and secure database-driven web applications.
**Future Trends and Other Considerations
**
The dynamism with which the technologies and best practices in database management systems change makes a new trend be ushered in daily. Key among these trends which the professional database expert must keep an eye on includes but is not limited to whether the adoption rate of cloud-based database services will increase or not; the increase rate of NoSQL database adoption; and if machine learning and AI will be integrated into the database management service.
**Conclusion
**
Database management makes it possible for a serious organization to make it in the modern world. With good understanding of core concepts, technologies, and best practices in database management, professionals give themselves a shot at becoming very important in this industry.
With the ever-growing need for data-driven web applications, the ability to merge database management skills with the craft of web development has become of critical importance. Web development courses, with modules on database management, would equip budding web developers and IT enthusiasts with much-needed skills to be able to design, develop, and maintain robust, scalable, and secure database-driven web applications that will position them successfully in the ever-evolving digital landscape. | jinesh_vora_ab4d7886e6a8d |

1,901,241 | Tracetest Monitors: Trace-based testing meets Synthetic Monitoring 🔥 | Are you ready to get your mind blown!? 🧠💥 Trace-based synthetic monitoring is here! You can now... | 0 | 2024-06-26T11:42:05 | https://tracetest.io/blog/tracetest-monitors-trace-based-testing-meets-synthetic-monitoring | monitoring, testing, programming, productivity | Are you ready to get your mind blown!? 🧠💥
Trace-based synthetic monitoring is here! You can now create “Monitors” for Tracetest tests and test suites.
Tracetest Monitors is a framework for creating scheduled runs of tests and test suites, and getting alerted when they fail. With native support for webhooks, you can choose how to integrate with you favorite alerting tools!
We’re dedicated to user experience and giving customers the easiest way of automating test runs without needing external CI tools. We want to give you the best possible tooling to embrace the “test in production” mindset too! Let’s be honest, we all do it! 😎
> [*Join our demo environment to try it out yourself!!*](https://app.tracetest.io/organizations/ttorg_2179a9cd8ba8dfa5/invites/invite_760904a64b4b9dc9/accept)
## The Problem — Scheduled Testing is Not as Simple as it Sounds
Test observability and trace-based testing has become a staple in the OpenTelemetry community. Having the power of distributed tracing at your fingertips when troubleshooting tests and writing assertions is immense. It’s highly advocated by the OpenTelemetry contributors in the official demo repository. While they, and all our other customers, are rolling their own automation with CI, to get the full benefit of trace-based testing, we’ve noticed it can often be a nuisance.
Configuring automated trace-based testing across multiple environments, using several tests, with a set timeframe of, let’s say, every 15 minutes, is not as simple as it sounds. You’d “just” need a CI tool of sorts, like GitHub Actions, or Jenkins. You’d maybe even settle for “just” creating a Kubernetes Job and defining it to run as a cron.
All of this is not as simple as using the word “just”.
Let’s normalize that “just” is relative and can’t apply the same to me, you, or someone else.
DevOps work like this can get exponentially more complex the more moving parts you introduce. A lot of the time SREs can get overloaded. That’s why shifting left and enabling the entire engineering team to perform synthetic testing in production, and across all your environments, is so powerful.
## The Idea — The Beginning of Synthetic Testing
We introduced the `Automate` tab back in July of 2023 including this [guide about simulating synthetic monitoring with GitHub Actions](https://tracetest.io/blog/github-actions-observability-slack-synthetic-api-tests).
Making trace-based synthetic monitoring a reality has been a dream since then. But, waking up from dreams takes you back to reality. Back in July of last year we were hyper-focused on releasing Tracetest Open Beta and making Tracetest widely available for our users as a cloud-based managed platform.
We’ve grown and matured since then. Finally, reaching a point where adding scheduled runs with Monitors has become reality!
## The Solution — Trace-based Synthetic Monitoring
The first-ever native synthetic monitoring tool for trace-based testing is live! Create a Monitor to run tests and test suites on a schedule.
Get alerted via webhooks by integrating with your favorite alerting tools.
Monitors leverage the existing Runs and Run Groups resources in Tracetest and build on top of it by enabling scheduling and alerting. Every Monitor you define will be presented as a Run Group with an additional tag using the specific name of the `Monitor`. Here you can see a list of Run Groups that include two Run Groups labeled as a `Monitor`.
Selecting the `#c85ea8f8-805d-4064-86ea-1aad2074e9c9` Run Group shows which tests are part of the `Monitor`.
Filtering Runs by the `Monitor` tag is also available in the Runs view.
Releasing Monitors as a Synthetic Monitoring feature has been a long-standing dream, and it has finally arrived. This is the culmination of almost a year of planning and laying the groundwork to launch it for you! Now you can finally get the full benefit of test observability and trace-based testing and easy-to-use test automation for both production and pre-production environments.
## How to Start Using Tracetest Synthetic Monitoring?
Make sure to use Tracetest `v.1.3.1` and above. There are no other requirements. Click on the `Monitors` tab, click `Create` and have fun!
## **What’s Next?**

An awesome feature of delegates are that you can chain methods together.
This enables you to create an instance of the delegate object and in one call, invoke multiple methods.
I think code below kind of explain itself.
```
class Program {
public delegate void mathCalculation(int a, int b);
public static void addition(int a, int b) {
Console.WriteLine($"Addition: {a + b}");
}
public static void multiply(int a, int b)
{
Console.WriteLine($"Multiplication { a * b}");
}
public static void Main (string[] args) {
mathCalculation add = addition;
mathCalculation mult = multiply;
mathCalculation chainMath = add + mult;
chainMath(10, 20);
chainMath -= add;
chainMath(10, 20);
}

1,901,239 | [AWS] The Future of Automobiles and Automated Driving [Generative AI] | This post introduces the contents of one session at AWS Summit Japan 2024. The content is about how... | 0 | 2024-06-26T11:40:57 | https://dev.to/reityerukohaku/aws-the-future-of-automobiles-and-automated-driving-generative-ai-3k9h | aws, ai, automateddrive | This post introduces the contents of one session at AWS Summit Japan 2024. The content is about how **AWS** and the latest **generated AI technologies** relate to the automotive industry.
## Conventional Automotives
Currently, the development of information and AI technology is bringing about a significant shift in the way cars are made. During this period of transformation, the concept of the **Software-Defined Vehicle (commonly known as SDV)** has appeared, and car manufacturers are dramatically changing the way they build cars in line with this concept. Furthermore, the recent boom in generative AI is opening new paths for autonomous driving technology. This includes enhancing autonomous driving technology using **LLMs (Large Language Models)**.
## Development of automated driving technology using LLMs
### Conventional automated driving technology
The below slide explains how the methods of achieving autonomous driving are changing.
At the AWS Summit, Turing Corporation introduced that the way of achieving autonomous driving is fundamentally changing. Until now, the mainstream method combines LiDAR and radar technologies to acquire and interpret surrounding information. However, currently, companies like Tesla and Turing Corporation are leading the research and development of systems that make decisions based solely on images captured by cameras, and they are fiercely competing in this field.
Thanks to the advancements in deep learning technology, autonomous driving is becoming possible using only cameras, without the need for LiDAR or radar. Compared to LiDAR and other sensors, cameras are relatively inexpensive, and their mechanism for situational judgment is closer to that of human drivers. Ideally, a camera-based system would be preferable.
### Contribution of Natural Language Models to Automated Driving
According to Li's research[^1], autonomous driving technology is evolving towards a more advanced understanding of situations by using natural language models. This is largely due to the recent remarkable advancements in LLMs.
The above slide explains that the learning tasks for autonomous driving are shifting towards those that use situational understanding through natural language.
However, LLMs cannot be directly used for autonomous driving because they cannot interpret images as they are.
### That's where multimodal models come in
Multimodal models are learning models capable of processing various types of data sources. Turing Corporation has introduced a method of further training advanced logical thinking LLMs with driving data such as videos. This approach enables the creation of multimodal models specialized for autonomous driving.
The above slide explains the way multimodal models can be trained quickly in large-scale distributed environments.
### AWS resources used for training
Turing Corporation achieved large-scale training of multimodal models by clustering AWS-provided [P5 instances](https://aws.amazon.com/ec2/instance-types/p5/?nc1=h_ls). In addition, they used [AWS ParallelCluster](https://aws.amazon.com/hpc/parallelcluster/?nc1=h_ls) for clustering, they were able to create an environment similar to a supercomputer.
It might seem like an expensive setup, but in 2023, they participated in the [AWS LLM Development Support Program](https://aws.amazon.com/jp/local/llm-development-support-program/) hosted by AWS Japan, a program where AWS covers part of the costs incurred during the development of LLMs. This allowed them to conduct the training.
### The completed multimodal model
The model created using the above method is available as open source! It is called Heron.
The above slide explains that by converting images into language tokens, LLMs are now able to interpret images.
### Methods of collecting training data
Data collection is also carried out using AWS resources. Various sensor data is collected using AWS IoT Greengrass. Data cleaning and sampling are also completed on AWS.
### Designing the architecture for running LLMs
Furthermore, Turing Corporation is also designing the architecture for running the developed multimodal model. This development utilizes FPGAs.
#### What's an FPGA?
An FPGA (Field Programmable Gate Array) is a circuit that does not have a predefined instruction set and can be reconfigured using a program. An FPGA contains numerous internal logic blocks and variable interconnects that can be configured through programming. This allows for the flexible construction of circuits with the necessary instruction sets, enabling the creation of circuits capable of performing operations such as the Softmax function used in LLMs.
### EC2 F1 instance
AWS offers EC2 instances equipped with FPGAs. This allowed Turing Corporation to conduct preliminary verification of their architecture design on AWS before developing actual FPGAs in a production environment.
## A bonus story about SDVs
From here, I'll share a bit about SDVs that were introduced in a separate session.
Traditionally, major functions and services in automobiles have been controlled by dedicated hardware. Engine, transmission, braking system, steering, and other functions operated independently, often requiring physical parts replacement or repairs for modifications. The characteristics of hardware-based development are as follows:
- Adding or improving functions requires the introduction of new hardware or physical modifications.
- Update frequency is low, and incorporating new technology takes time and costs.
- The role of software is limited, primarily used to control hardware.
On the other hand, SDVs define and control the vehicle's major functions and services through software. This new approach offers flexibility and quick updates. The characteristics of SDVs are as follows:
- New functions and services can be added or improved through software updates, eliminating the need for physical parts replacement.
- Real-time updates are possible via over-the-air (OTA) updates.
- Data-driven development ensures that the vehicle is always up to date, enhancing the user experience.
### A story that personally excited me
In the future, autonomous driving technology may develop further, and we might use autonomous driving in our daily lives. However, I personally enjoy driving myself, so I might feel a bit sad if I could only drive an autonomous car.
But if SDV becomes mainstream, we might be able to realize use cases like the following:
- Autonomous driving for everyday use
- Switching the car to a racing tune for enjoying motorsports on weekends!
Imagine if car manufacturers provide a page on AWS where users can configure various settings for the motor and electronic control suspension, allowing the vehicle's behavior to change dynamically. Wouldn't that be incredibly exciting?
As a fan of Gran Turismo, the thought of being able to freely tune my car excites me greatly!
## Conclusion
The automotive environment is rapidly changing and evolving, driven by the advancements in cloud and AI technology. What is considered cutting-edge technology today might become outdated a year from now. This rapid pace of evolution makes us feel that way.
Moreover, the concept of SDVs is expected to offer us users a more flexible and enjoyable way to experience cars. Behind the scenes, cloud providers like AWS are likely playing a crucial supportive role.

series: Delegates and events in C# made easy.
---
Are you confused about delegates in C#? No worries, this guide will get you covered!
### Overview of delegates in C#.
Delegates are type-safe and secure objects that enable powerful features for methods.
They allow you to pass methods by reference, and because of that, methods can be stored as variables, passed by reference, and chained together.
Delegates are used when working with events, creating callback functions, and adopting the functional programming paradigm in C#.
Delegates make the code concise and readable, especially when dynamically invoking methods. By dynamically invoking methods, I mean methods that are called during runtime with conditions or arguments only known at runtime. User input is a good example of this.
Delegates are highly adopted and used in event driven programming.
## implementation
First implement a delegate type. Use the keyword `delegate` followed by the method signature, the `return type` and `parameters`.
```
public delegate int mathCalculation(int a, int b);
```
This delegate method is called `mathCalculation` and obviously is a signature for calculating something.
Any method from any accessible class or struct that matches this signature can be assigned to the delegate.
#### Create 2 math operation methods with the same signature.
```
public int addition(int a, int b) {
return a + b;
}
public int multiply(int a, int b)
{
return a * b;
}
```
#### Assign the methods to the delegate object.
```
// Use the delegate name to create 2 varibles
mathCalculation add;
mathCalculation mult;
// Assign the methods to the varibles.
add = this.addition;
mult = this.multiply;
// Execute
int addResult = add(10, 20);
int multResult = mult(10, 20);
Console.WriteLine($"Addition result: {addResult} multiply result: {multResult}");
```
#### Optionally use short hand methods.
Short hand functions cannot be used outside the class but are fast and concise.
```
add = (int a, int b) => a + b;
// leave out the types.
mult = (a, b) => a * b;
```
### Full example
```
class Program {
public delegate int mathCalculation(int a, int b);
public static int addition(int a, int b) {
return a + b;
}
public static int multiply(int a, int b)
{
return a * b;
}
public static void Main (string[] args) {
// Use the delegate name to create 2 varibles
mathCalculation add;
mathCalculation mult;
// Assign the methods to the varibles.
add = addition;
mult = multiply;
// Execute
int addResult = add(10, 20);
int multResult = mult(10, 20);
Console.WriteLine($"Addition result: {addResult} multiply result: {multResult}");
}
}
```
### Short hand version
```
class Program {
public delegate int mathCalculation(int a, int b);
public static void Main (string[] args) {
mathCalculation add = (a, b) => a + b;
mathCalculation mult = (a, b) => a * b;
int addResult = add(10, 20);
int multResult = mult(10, 20);
Console.WriteLine($"Addition result: {addResult} multiply result: {multResult}");
}
}

1,901,237 | Understanding Soroban | Stellar Smart Contract Platform | Stellar is an open-source blockchain that enables global economic transactions. Supported by a $100... | 0 | 2024-06-26T11:37:57 | https://dev.to/donnajohnson88/understanding-soroban-stellar-smart-contract-platform-acf | stellar, soroban, smartcontract, webdev | Stellar is an open-source blockchain that enables global economic transactions. Supported by a $100 million adoption fund from the Stellar Development Foundation, this blockchain has pre-released Soroban to facilitate the building and deployment of Stellar smart contracts (SSC).
This article will help you understand this [Stellar blockchain development](https://blockchain.oodles.io/stellar-blockchain-development-services/?utm_source=devto) for smart contracts, its use cases, and more.
## What is Stellar Blockchain?
[Stellar](https://stellar.org/) is an open-source and decentralized global trading network that enables inexpensive transfers between digital currency and fiat money. Also, it allows cross-border currency exchanges between any two currencies. It uses blockchain technology, just like other cryptocurrencies, to maintain network synchronization.
Stellar is speedier, less costly, and more effective than existing blockchain-based financial access and inclusion systems. Stellar Lumens (XLM) is its native coin, facilitating international transactions.
One of Stellar’s key features is its focus on financial inclusion. Thus, Stellar aims to make financial transactions more efficient, affordable, and accessible to people worldwide, particularly those currently underserved by traditional banking systems.
It offers an efficient system for fast and low-cost digital asset issuance and transfer.
**Stellar Smart Contracts (SSC)**
Smart contracts define and secure connections via computer networks by integrating user interfaces and protocols. The goals and guiding principles of smart contract development come from concepts of secure protocols, economic theory, and legal principles.
Smart contracts are expressed as Stellar smart contracts (SSCs) on the Stellar network. Connected transactions inside an SSC operate under various limitations.
When developing SSCs, the following constraints can be taken into account and implemented:
**Multisignature**
Multisignature refers to a concept in which different people must sign transactions from an account. People can also assign thresholds and signature weights.
**Atomicity/Batching**
Several operations are combined into a single transaction under the batching principle. If one operation in a transaction fails, atomicity causes the transaction as a whole to fail.
**Sequence**
Sequence numbers represent sequences on the Stellar network. The blockchain utilizes these sequence numbers to regulate transactions and ensure that transactions fail if a substitute is present.
**Time Bounds**
Time bounds set limits on how long a transaction can be valid. They express periods in an SSC.
## Soroban — a Smart Contract Platform
[Soroban](https://soroban.stellar.org/docs) is a smart contract platform for the Stellar network. Based on WASM (web assembly) and Rust, the Stellar network supports Soroban’s Turing-complete smart contracts. When combined with the strength of the Stellar network, Soroban on Stellar will enable use cases focused on extending access to financial services.
Founders created this new type of smart contract platform for the built-to function. A preview of Soroban is live on Futurenet. Now, developers can start building and deploying smart contracts on a test system with Soroban and earn rewards for their work.
Founders built Soroban for scalability, a battery-included developer experience, and reliable access to financial channels via the Stellar network.
## Soroban Design Principles
Founders developed Soroban to perform through the following three design principles:
**Battery-included**
The intention behind creating Soroban is to provide developers with a battery-included experience. Developers have direct access to the resources they need to start quickly and deploy solutions successfully.
Soroban developers will have access to a Local sandbox for quick setup and iterative development. As a result, they can run and debug their contracts independently, locally, and without the assistance of the Stellar network.
A comprehensive and effective set of host functions and built-in contracts are also available to save time. One such function is a built-in efficient token contract that eliminates the need to copy and paste ERC-20 contracts.
**Scalability**
Another principle of Soroban is scalability. The platform offers a base that can support concurrency immediately. Soroban transactions comprise footprints as transaction dependencies. They use contemporary multi-core hardware to run group transactions simultaneously.
Soroban has a limited number of deserialization and serialization loops. The smart contract development process is easy as the platform does not have encoding and decoding, which consumes significant time and computer resources.
**Access to Financial Rail**
Soroban creates trusted connectivity to financial networks via the Stellar network. Creators integrated Soroban into the current Stellar ecosystem and tech stack, allowing developers to take full advantage of Stellar’s strengths as a tested, reliable network.
## Stellar Smart Contract Use Cases
The following are the SSC use cases:
**Digital Identity and NFTs**
Developers can use Stellar smart contracts for non-fungible tokens (NFTs). People can convert their gaming assets, certifications, credentials, and more into digital assets on the Stellar blockchain. The blockchain stores the metadata of these assets. Stellar smart contract code configures the metadata to determine ownership and reassign the same with the NFT.
**Decentralized Finance (DeFi)**
Stellar smart contracts (SSCs) enable the functioning of decentralized finance (DeFi) solutions, including borrowing, lending, tokenization, payment apps, and more. DeFi businesses utilize them to protect the atomic escrow account. Here, SSCs’ regulations control the assets. Programs will only release these assets after the fulfillment of certain conditions.

I'm still... | 0 | 2024-06-26T11:32:00 | https://eevis.codes/blog/2024-06-26/the-worst-case-of-imposter-syndrome/ | career, mentalhealth, developers, life | I wrote most of this blog post in the spring, a bit after my burnout sickness leave. I'm still recovering, but I'm in a way better place. I found this draft a couple of days ago, and after reading it, I decided I'd finish it and publish it. Why? I think it speaks for itself. It contains the words I'd wanted to say back then but didn't have the strength to say, even to finish the blog post and share it.
And if you recognize yourself from the words, I see you. You are enough and have what it takes, even if it doesn't feel like it.
## The Worst Case of Imposter Syndrome
I think I'm experiencing the worst case of imposter syndrome in my career. It's so bad that I've started considering switching careers because I can't stand this deep feeling. And when I say switching careers, I'm not joking the way I usually joke when something mysterious happens with the code. No, this time, I've been considering leaving tech behind.
It all started... Where it all started? I don't even know. For a long time, I've been really confident. Not in an arrogant way, but in a way that I know what I know, and I definitely know what I don't know. And sure, I've had setbacks, but I've always bounced back.
Now it just feels like I'm going deeper and deeper into understanding how much I suck. And how little I know and how I shouldn't even work in this position. How everyone knows that I'm a fraud.
I can start dissecting this. And actually, that's what I'll do. I'll tell you about some things that have led to this situation. It's not because I blame someone (or actually, I do - myself), but I want to bring light to things that have caused my journey to end up here.
Oh, and in the end, I won't tell you how to get better. This is not one of those blog posts. I'm still on my way to getting out of the woods with all this. But I hope reading what has affected me might help you recognize some things on your journey that might lead to where I am and avoid them. This is most definitely not a fun place to be.
## Burnout Leads to Questioning Yourself
Burnout can cause low professional self-esteem, so it's no wonder it can be one of the building blocks for imposter syndrome. It's sneaky and builds over time, so the change is not always easy to spot.
My advice: Don't get burnt out. Do something before it's too late. I know it's not always easy to recognize that you're on the path to burning out. Heck, I've been here many times, and I still don't always recognize it well enough.
## The Words of Others Can Do a Lot of Harm
To add to this burnout-related low self-esteem, hearing words like "this is what senior developers should know" and realizing you don't know all that doesn't help. I was part of a hiring committee for a senior Android developer role a while back, and at some point, I realized how others described what a senior Android developer should know.
It was all technical details - trivial things I realized I didn't know to describe on the spot. And the way they talked about the candidates and their skills, I just felt like I should get a demotion because I don't have all the technical knowledge for a senior developer. Maybe not even for a mid-level developer.
Hearing those conversations, I was ready to quit. I felt like I'm not good enough (despite being in a senior Android role for more than a year, so I had literally proven myself already). I felt like every single one of my Android colleagues must see me in a way that I don't deserve to be a _senior_ developer, and that I was just lucky to get promoted.
That feeling is paralyzing. You start to question your every decision and every line of code. You start waiting for something bad to happen, and every time there is a crash or bug that's reported, you're sure that it's because of you (even if you haven't merged any code for the past weeks because you were on a sickness leave).
I'm getting better now, but this feeling and those thoughts are still nagging me. I can fight them, but I realize they affect the things I do a lot. Luckily, I have a colleague who keeps cheering me on and reminding me that I am skilled and good enough (thank you, Marianne ❤️). But I really hope that no one needs to go through those emotions I've gone through. So, let's remember that our words affect people around us.
## Constant Fighting for Your Seat at the Table Does Not Help
The other thing that contributes to this feeling is the constant fight to be heard and seen. I've been in countless meetings where I've been forgotten - like, let's have a facilitated round of introductions, but let's forget Eevis. At the time, I was so exhausted that when that happened, I was just silently crying and could not open my mic to say, hey, I'm here; please don't forget me again.
I often have felt like I'm speaking to walls. Or maybe something else, walls often don't answer with "Oh that's a good point" and then forget it all when it's time to incorporate the feedback.
I could also talk about the countless times when I've been the person who knows the answer to something because I've been the one working with the thing. And then, in some meeting, I'll need to first wait for some man, who has just a vague idea of that thing, to explain what's going on - and then start correcting them. Yes, I'm too nice to just cut there when they start. No, I won't change that; it requires even more strength. I've been raised to be nice, polite, and not cut when others speak.
I fully believe that none of these people do these things because they hate me or consciously think I'm lesser. But nevertheless, they keep repeating these actions, and it tires me out. I hate the constant fighting. I'd like to have a seat at the table because I've already earned it (because, trust me, I have). I hate playing this constant chair game where I need to prove myself over and over again, more than many of my colleagues do.
I've described this all working twice as much as many others. And in fact, I do. So, it is no wonder I am burnt out and exhausted. And no wonder I have this feeling that even if I work twice as much, I'll never be good enough as the others who don't need to work that much.
## Wrapping Up
If you're my colleague reading this and recognize yourself from what I've written, I'm not blaming you. I fully believe you have good intentions in every instance. I'm just asking that you pay attention to the impact your actions might have — not just on me but on anyone around you.
And if you're experiencing similar things, I'd love to say things get better, but I have to be honest: I don't know if they do. I know it's possible to reach this state of mind where you're confident and small things don't affect you. I've been there. And I hope I'll reach that state some day again.
But before that, I hope I won't end up switching careers.

1,901,235 | Next.js Authentication Best Practices | Explore key Next.js authentication best practices, including middleware vs. page component auth, preserving static rendering, and implementing multi-layered protection. | 0 | 2024-06-26T11:31:21 | https://www.franciscomoretti.com/blog/nextjs-authentication-best-practices | nextjs | ## What is Next.js Authentication?
Next.js authentication is the process of verifying user identity in Next.js applications. It ensures that only authorized users can access protected routes and data.
Authentication in Next.js is crucial for:
1. Protecting sensitive user data
2. Controlling access to specific features
3. Personalizing user experiences
4. Maintaining application security
Understanding Next.js authentication best practices is key to building secure and efficient web applications.
## Middleware vs. Page Component Authentication
Next.js provides two main approaches to authentication: middleware and page component authentication. Let's explore both:
### Middleware Authentication
Middleware authentication offers several advantages:
* Cleaner structure for managing authentication across routes
* Preserves static rendering capabilities
* Better performance, especially with JSON Web Tokens (JWTs)
Here's a simple example of middleware authentication:
```tsx
import type { NextRequest } from 'next/server'
export function middleware(request: NextRequest) {
const currentUser = request.cookies.get('currentUser')?.value
if (currentUser && !request.nextUrl.pathname.startsWith('/dashboard')) {
return Response.redirect(new URL('/dashboard', request.url))
}
if (!currentUser && !request.nextUrl.pathname.startsWith('/login')) {
return Response.redirect(new URL('/login', request.url))
}
}
export const config = {
matcher: ['/((?!api|_next/static|_next/image|.*\\.png$).*)'],
}
```
### Page Component Authentication
Page component authentication has its own benefits:
* Can be implemented directly in the page file
* Offers more flexibility for page-specific auth logic
Here's an example of page component authentication:
```tsx
import { redirect } from 'next/navigation';
import { checkAuth } from '@/lib/auth';
export default async function ProtectedPage() {
const isAuthenticated = await checkAuth();
if (!isAuthenticated) {
redirect('/login');
}
return (
<div>
<h1>Protected Content</h1>
{/* Page content here */}
</div>
);
}
```
> 💡 Tip: Choose middleware for better performance and cleaner code structure, especially for apps with many protected routes.
## Avoiding Authentication in Layout Components
It's important to avoid implementing authentication checks in layout components. Why? Layout components don't re-render on client-side navigation, which could leave routes unprotected.
## Preserving Static Rendering
Static rendering is a key performance feature in Next.js. To preserve it:
1. Use middleware for authentication when possible
2. Don’t add authentication inside specific routes (pages).
Adding authentication inside a page makes it dynamic. However, many times the extra security layer benefit outweighs the performance improvement.
## Authentication for Server Actions
Server actions are a new feature in Next.js that allow server-side processing directly from client components. When using server actions:
1. Implement authentication checks within the server action itself
2. Don't rely solely on page-level or middleware authentication
Server actions are like API routes. They could be called by an external user by calling the server action URL directly.
## Proximity Principle
The proximity principle suggests keeping authentication checks as close as possible to where data is accessed or used. This means:
1. Implementing checks in reusable components that handle sensitive data
2. Adding auth logic directly in data fetching functions
Here's an example of applying the proximity principle:
```tsx
async function fetchUserData(userId: string) {
const isAuthenticated = await checkAuth();
if (!isAuthenticated) {
throw new Error('Unauthorized');
}
// Fetch and return user data
}
```
## Multi-layered Approach
A robust authentication strategy in Next.js involves multiple layers of protection:
1. Use middleware or page-level checks as a first line of defense
2. Implement additional checks at the page and data access levels
Here's a simplified example of a multi-layered approach:
```tsx
// Middleware (first layer)
export function middleware(request: NextRequest) {
// Check for auth token
}
// Page component (second layer)
export default function ProtectedPage() {
const { user } = useUser(); // Custom hook for user data
if (!user) return <LoadingOrRedirect />;
return <ProtectedContent user={user} />;
}
// Data fetching (third layer)
async function fetchSensitiveData() {
// Check auth and permissions before fetching
}
```
## Conclusion
Next.js authentication best practices involve a combination of techniques:
1. Use middleware for app-wide auth when possible
2. Implement page-level checks for specific routes
3. Apply the proximity principle for data access

1,901,232 | How Marketing Leaders Can Gain Greater Alignment with IT | In today’s digital landscape, the intersection of marketing and technology is more crucial than ever.... | 0 | 2024-06-26T11:24:58 | https://dev.to/keval_padia/how-marketing-leaders-can-gain-greater-alignment-with-it-407j | In today’s digital landscape, the intersection of marketing and technology is more crucial than ever. Marketing leaders need to collaborate seamlessly with IT departments to leverage technological advancements, streamline processes, and drive business growth. However, achieving alignment between marketing and IT can be challenging due to differing priorities, terminologies, and workflows. Here are several strategies marketing leaders can implement to bridge this gap and foster a collaborative environment with their IT counterparts.
**1. Develop a Unified Vision**
Both marketing and IT departments must share a common vision that aligns with the organization's overall objectives. Marketing leaders should work with IT to create a unified strategy that addresses the needs of both departments. This involves:
Setting joint goals: Establish clear, measurable goals that benefit both marketing and IT. For instance, improving customer data management can enhance marketing campaigns while ensuring data security and compliance.
Defining roles and responsibilities: Clearly outline the roles of each team member to avoid confusion and overlap. This clarity will streamline collaboration and ensure accountability.
**2. Foster Open Communication**
Effective communication is the cornerstone of any successful partnership. Marketing leaders should:
Regular meetings: Schedule regular meetings with IT counterparts to discuss ongoing projects, challenges, and upcoming initiatives. This keeps everyone on the same page and allows for timely problem-solving.
Cross-functional teams: Create cross-functional teams comprising members from both marketing and IT. This fosters a collaborative culture and ensures diverse perspectives are considered.
**3. Invest in the Right Tools**
Technology can either be a bridge or a barrier between marketing and IT. Choosing the right tools can enhance collaboration:
Integrated platforms: Utilize integrated marketing platforms that offer seamless data sharing and collaboration features. Tools like CRM systems, marketing automation platforms, and analytics software should be compatible with existing IT infrastructure.
Project management software: Adopt [project management tools](https://www.nimblechapps.com/blog/top-7-project-management-tools-to-use-in-2024) that both marketing and IT teams can use. Platforms like Asana, Trello, or Jira help track progress, manage tasks, and facilitate communication.
**4. Enhance Mutual Understanding**
Marketing and IT often speak different languages—one focused on creativity and customer engagement, the other on technical precision and security. To bridge this gap:
Cross-training: Encourage team members to learn the basics of each other's fields. Marketers should have a basic understanding of IT concepts, while IT professionals should grasp marketing fundamentals.
Workshops and training sessions: Organize workshops and training sessions where each team can present their workflows, challenges, and objectives. This promotes empathy and a better understanding of each other's work.
**5. Prioritize Data Security and Compliance**
With the increasing emphasis on data-driven marketing, data security and compliance have become critical concerns. Marketing leaders must:
Collaborate on data governance: Work closely with IT to establish robust data governance policies. This ensures that customer data is handled securely and in compliance with regulations such as GDPR or CCPA.
Implement best practices: Follow IT's guidance on best practices for data security, such as encryption, access controls, and regular audits. This not only protects sensitive information but also builds trust between departments.
**6. Celebrate Successes Together**
Acknowledging and celebrating joint successes can strengthen the relationship between marketing and IT:
Highlight collaborative achievements: Showcase successful projects that resulted from effective collaboration between marketing and IT. This recognition boosts morale and demonstrates the value of working together.
Reward teamwork: Consider implementing reward systems that incentivize collaboration. Recognizing team members who exemplify cross-departmental cooperation can encourage others to follow suit.
**Conclusion**
Achieving greater alignment between marketing and IT is essential for leveraging technology to drive marketing success. By developing a unified vision, fostering open communication, investing in the right tools, enhancing mutual understanding, prioritizing data security, and celebrating successes together, marketing leaders can build a strong, collaborative relationship with their IT counterparts. This synergy not only enhances the effectiveness of marketing initiatives but also contributes to the overall growth and success of the organization. | keval_padia | |

Now it's open\-source\!" This incredible news is a call to action for us\. The project code has been checked, errors have been detected, and the first part of the article is ready to be read\. It's showtime\!
## Few words about project
On March 6, 2024, Intel released the OpenVINO source code\. So, what is OpenVINO? First, it's the tool that aids developers in effectively training AI computer vision\.
<spoiler title="What is computer vision in brief?">
Computer vision is a technology that helps us identify and interpret certain data in visual images taken from video of sufficient quality\. It's hard for human eyes, but camera and trained AI won't let any white rabbit escape\.
It's also worth noting that computer vision is really handy, and helps in many fields, for example:
1. Sorting and grading the agricultural products;
1. Classifying and spotting manufacturing defects in various electronic modules and components;
1. Industrial automation;
1. Facial recognition systems;
1. Medical purposes: in colonoscopy, in vision therapy, or in brain disease detection\.
It's not a whole list of options, but that's not the point of this article\. Whatever, we can't argue that AI\-powered technologies are highly beneficial\. Various deep learning tools are being developed to make all these possible\. One of such tools is OpenVINO\.
</spoiler>
To be more precise, OpenVINO is a free ready\-to\-use toolkit that developers can use to accelerate the development of such solutions\. So, as well as the AI training tools, there are also tools for checking the AI effectiveness and its own benchmark\. That's about it\.
Trying timidly to touch this work of art with my crooked fingers, I pulled the PVS\-Studio static analyzer out of holster to dive into the project code and search for some alien entities aka bugs\. The result will surprise you\.
Even with the bugs, the tool still works as it's supposed to: AI learns and operates well \(if we judge by the endless number of dev articles\)\.
You won't encounter such a case in training your AI:
> Dev: AI, I can't feel my computer vision\!
>
> AI: Meow?\!
The commit I built the project on for checking it: [2d8ac08](https://github.com/openvinotoolkit/openvino/tree/2d8ac08bf1f87f8ac455eae381213b52e781fe8c)\.
<spoiler title="Disclaimer">
The article has no purpose to depreciate the labor of the OpenVINO developers\. The aim is to popularize the use of static code analyzers, which can be of great assistance even for high\-quality and successful projects\.
</spoiler>
## Check results
The checked project is full of typos and issues that occur when developers use copy\-paste\.
That's why I decided to write a separate article to highlight that such errors can be found almost in any project\.
Indeed, the programmer might intend it that way\. However, this chance is\.\.\. very low\.

As you can see, the bottom condition compares two identical expressions—the same calls to the *std::any\_of* function with the same parameters\. I added the code above for a reason\. If you take a look at it, you'll see that the condition should probably have been written as follows:

Here we go again: there is another error in the condition\. The same expression is checked twice: the *reshape\_after* pointer is non\-null\. If we look at the code above again, we notice the *reshape\_before* initialization\. I think the condition should be rewritten as follows:

We face a tricky error here\. Let's break it down\.
First, we see that it's checked whether the *m\_pattern\_value\_maps* vector is empty\.
Then we notice that in the *then* branch of the second nested *if*, another *m\_matcher\-\>m\_pattern\_value\_maps* is handled for some reason\. From bad to worse\.
The *std::vector<PatternValueMap\>::erase* member function of the *m\_matcher\-\>m\_pattern\_value\_maps* container is passed arguments as iterators of another *m\_pattern\_value\_maps* container\. It won't operate correctly\.
It follows from the [constructor](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/src/pattern/matcher.cpp#L19-L23) and [destructor](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/src/pattern/matcher.cpp#L40-L54) that the *MatcherState* class is designed to revert changes to an [object](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/include/openvino/pass/pattern/matcher.hpp#L35) of the *Matcher* type\. The RAII wrapper code might have been used to contain the state of the *Matcher* object in the *MatcherState::m\_pattern\_*value*\_map* and *MatcherState::m\_pattern\_value\_maps* [data members](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/include/openvino/pass/pattern/matcher.hpp#L36-L37) and then return it in the destructor\.
However, devs rewrote the code to add the *MatcherState::m\_watermark* and *MatcherState::m\_capture\_size* [data members](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/include/openvino/pass/pattern/matcher.hpp#L38-L39)\. Devs are responsible for deleting elements that have been added to the end of the *Matcher::m\_matched\_list* and *Matcher::m\_pattern\_value\_maps* [containers](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/core/include/openvino/pass/pattern/matcher.hpp#L177-L178)\.
So, here's what we need to fix the code:
```cpp
if (!m_matcher->m_pattern_value_maps.empty())
{
m_matcher->m_pattern_value_maps.erase(
m_matcher->m_pattern_value_maps.begin() +
m_capture_size,
m_matcher->m_pattern_value_maps.end() );
}
```
I'd also like to point out that the *MatcherState::m\_pattern\_value\_maps* data member is no longer used, so we may delete it\.

It's bizarre that in the second condition, the *coord::h* constant is checked\. Indeed, it has the value of 1, and such code will always return *true*—it's clearly an error\.
In this case, the code in the body of the last *else* branch won't be executed\. What is it? Is it a tricky developers' idea, or is it an artificial limitation for the executable code? It looks more like a bug\. There should be the *dim == coord::h* expression in the condition\.

Here are a few more warnings to see the full picture:
1. V547 Expression 'kernel\_size\.size\(\) == 2' is always true\. im2col\.cpp 67
1. V547 Expression 'kernel\_size\.size\(\) == 2' is always true\. im2col\.cpp 69
At first glance, it's not clear what the analyzer is trying to tell us with all these warnings, but let us speculate\.
The first thing that catches your eye is that the *kernel\_size\.size\(\) == 2* is checked four times\. The *kernel\_size* vector doesn't change anywhere after the first check\. The analyzer suggests that the following three checks are always true\.
How did the analyzer figure that out?
The *PYTORCH\_OP\_CONVERSION\_CHECK* macro has the *create* [function](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/frontends/common/src/exception.cpp#L40-L50) that throws an exception if the expression passed to the macro yields to *false*\. Hence, the *kernel\_size\.size\(\)* expression should be equal to 2 for all code to be reachable after the check\. By default, we consider it as such\.
Next, you might ask, "Why do we even need to check the *kernel\_size\.size\(\)* value if the *kernel\_size* vector doesn't change and its size will always be 2?" Everything we looked at earlier was just a result of the mistake, not the reason\. The reason is simple\.
The *kernel\_size* object was created and initialized, and then the *kernel\_size\.size\(\) == 2* expression was passed to the *PYTORCH\_OP\_CONVERSION\_CHECK* macro and checked inside\. Another *dilation* object was created, but the *kernel\_size\.size\(\) == 2* expression was passed to the *PYTORCH\_OP\_CONVERSION\_CHECK* macro as well\. Although, from a logical standpoint, the *dilation\.size\(\) == 2* expression will be passed and checked\.
If you pay attention to the second argument as string passed to the macro, then again, it becomes obvious that the *size* function should be called for the *dilation* object\. And the same is for other two objects, you get it\.\.\. The programmer copied code lines and forgot to change the objects names for which they passed size checks as a parameter to the macro\.

```
The analyzer warning:

As we can see, the same expression is checked\. Nothing wrong will happen, but one redundant expression is better to delete\.

The analyzer warning:

The condition checks the same subexpression for inequalities\. There might be a copy\-paste issue here\. Since devs directly wrote, "*has different ranks for input and output tensors,*" and we consider that there is a similar function but for the *output* values as at the following code:
```cpp
const Shape& getOutputShapeAtPort(size_t port) const
{
if (outputShapes.size() <= port)
{
OPENVINO_THROW("Incorrect output port number for node ", getName());
}
return outputShapes[port];
}
```
We may fix the code as follows:
```cpp
if (getInputShapeAtPort(0).getRank() != getOutputShapeAtPort(0).getRank())
{
OPENVINO_THROW(errorPrefix,
"has different ranks for input and output tensors");
}
```

OPENVINO_ASSERT(state->get_byte_size() ==
state->get_byte_size(), // <=
"Blob size of tensors are not equal.");
std::memcpy(m_state->data(), state->data(), state->get_byte_size());
}
```
The analyzer warnings:
1. V501 There are identical sub\-expressions 'state\-\>get\_element\_type\(\)' to the left and to the right of the '==' operator\. [variable\_state\.hpp](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/plugins/template/src/variable_state.hpp) 23

The first line compares the *state\-\>get\_shape\(\) *and *m\_state\-\>get\_shape\(\)* expressions\. However, the following lines compare the results of calling the *get\_element\_type* and *get\_byte\_size* member functions of the same *state* object because of copy\-paste\. Most likely, it happened because the names of *m\_state* and *state* are similar—the programmer didn't pay attention to it\.
Let's fix the code:
```cpp
....
OPENVINO_ASSERT(state->get_element_type() ==
m_state->get_element_type(),
"Wrong tensor type." );
OPENVINO_ASSERT(state->get_byte_size() ==

If we pay attention to the *std::find\_if* function call, we notice that the second argument should be a call to *new\_inputs\.end\(\)*\. In the current state, the code always returns *new\_inputs\.begin\(\)*\.

}
return inConfs[portNum].getMemDesc(); // N2

It looks like the code is fine, and the analyzer warns for nothing\. But no such luck\. To make it easier to explain, I've marked the lines that we should focus on\.
The line N1 in the condition checks the *inConfs\.size\(\) < portNum* expression\. The condition becomes *false* when *portNum <= inConfs\.size\(\)*\. The *inConfs* container is then accessed in the line N2\. The container should be accessed by indices in the range of \[0 \.\.\. N \- 1\]\. However, in the boundary case, when we have *portNum == inConfs\.size\(*\), we'll catch a container overrun, leading to undefined behavior\.
The fixed check should look like the following:
```cpp
if (portNum >= inConfs.size()) { .... }
```
I also switched the operands around because, in my opinion, it's easier for developers to read such a check\.
Upon reading about the error, the reader may call on Peter to explain the situation: "There are no typos or copy\-paste problems in this example, then why is it here?" The point is that this error has been repeated:
```cpp
....
std::vector<PortConfig> outConfs;
....
MemoryDescPtr Node::getBaseMemDescAtOutputPort(size_t portNum) const
{
if (auto primDesc = getSelectedPrimitiveDescriptor())
{
const auto& outConfs = primDesc->getConfig().outConfs;
if (outConfs.size() < portNum) // <=
{
OPENVINO_THROW("Can't get output memory desc at port: ",
portNum, ", incorrect port number" );
}
return outConfs[portNum].getMemDesc(); // <=
}
OPENVINO_THROW("Can't get output memory desc,
primitive descriptor is not selected");
}
```
The analyzer warning:
[V557](https://pvs-studio.com/en/docs/warnings/v557/) \[CERT\-ARR30\-C\] Array overrun is possible\. The 'portNum' index is pointing beyond array bound\. [node\.cpp](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/plugins/intel_cpu/src/node.cpp) 413
These two functions are almost the same\. It seems like developers just copied one function and then made a few tweaks\. They renamed a local variable, used different object data members and changed an exception message\. However, the error also migrated to the second function\.
Let's fix it:
```cpp
if (portNum >= outConfs.size()) { .... }
```
In general, it'd be better to refactor the code—turn these two functions into one common function and then reuse it\.

It's amusing that many devs think it's pointless to look for errors in such code\. So, they just scroll down to see an answer right away\.
There's also an irony in how, despite weighting up inefficiency and labor costs, developers still monotonously search for errors without using static analyzers\.
It's so simple: take the analyzer, run the analysis, look at the list of errors\. Profit\. No need to waste time looking for bugs—they're already highlighted\. Just fix them and that's all\.
The analyzer warnings:
1. [V766](https://pvs-studio.com/en/docs/warnings/v766/) An item with the same key '"Abs"' has already been added\. [cpu\_types\.cpp](https://github.com/openvinotoolkit/openvino/blob/2d8ac08bf1f87f8ac455eae381213b52e781fe8c/src/plugins/intel_cpu/src/cpu_types.cpp) 178

Briefly, here are the typos:
```cpp
static const TypeToNameMap& get_type_to_name_tbl() {
static const TypeToNameMap type_to_name_tbl = {
....,

{"Abs", Type::Math}, // <=

{"SoftPlus", Type::Math}, // <=

};
return type_to_name_tbl;
}
```
Clearly, there should not be identical values here, and developers should never use duplicates\.
## Conclusion
What a fascinating typo adventure we've had\!
The first part of the article about checking the OpenVINO project comes to the end\. May the force of accuracy and concentration be with you\!
We'll send all the bugs to the developers and hope the they will get fixed soon\.
Just a quick reminder: the typos and other errors we've spotted only show that programmers are human too\. To be happy and to fix errors in code, all they need is a small, efficient, and their own static analyzer\.
Traditionally, I'd suggest you [try](https://pvs-studio.com/en/pvs-studio/try-free/?utm_source=website&utm_medium=devto&utm_campaign=article&utm_content=1137) our PVS\-Studio analyzer\. We have a [free](https://pvs-studio.com/en/order/open-source-license/) license for open\-source projects\.

1,900,059 | Introducing the Organic Feed Feature in Lambda! | Hey everyone, I’m EzpieCo (well, not my real name), the creator and sole developer behind Lambda, the... | 0 | 2024-06-26T11:19:01 | https://dev.to/ezpieco/introducing-the-organic-feed-feature-in-lambda-37bg | privacy, webdev, opensource | Hey everyone, I’m EzpieCo (well, not my real name), the creator and sole developer behind Lambda, the world's first open-source social media app designed to prioritize your privacy and well-being. I’m thrilled to share some exciting updates with you today!
## 🌟 What’s New?
Yesterday after some hard work, I have rolled out the most important feature of any social media app, The Feed. Here’s what it means for you:
- **Organic Feed:** Keeping privacy and well-being in mind I have focused the feed to be generated using only the posts created by those people whom you follow, this means no other user's posts which is relevant and has a higher click rate won't be shown on your feed. Thus prioritizing your privacy.
### What it means technically
If you want a technical point of view here you have it!
In more traditional social media apps, feeds are generated using a simple rule of thumb, which is more inorganic and less organic. This means that the feed contains content created majorly by those users who have relevant content and a higher click rate to make sure you stay on the site for longer exposure to ads, thus increasing the chances of clicking on ads.
_Simple demonstration of how it works_
This leads to an infinite scroll which you can never meet an end to(unless you give it all you got). Thus also leading to bad well-being.
To counter this Lambda generates your feed using only posts from the people you follow. This means the person whom you follow only their posts are shown in your feed while for others you will still need to search and follow them to get their posts in your feed.
_Lambda feed generating algorithm_
As you can see it does not take anything, it just simply does an HTTP request to the database and gets the usernames of people you are following, then it gets all their posts and arranges those in order of latest, and there you have it! Your feed is generated!
## 🚀 How You Can Get Involved
Lambda is still in its early stages, and your support can make a huge difference! Here’s how you can help:
- **Star us on [GitHub](https://github.com/ezpie1/lambda-official):** Show your support by starring the project.
- **Create a [Lambda account](https://lambda-official.vercel.app/):** Sign up and explore the new features.

- Spread the Word: Share Lambda with your friends and family. Every new user helps us grow!
## 💬 Join the Conversation
I’m always around to discuss Lambda, answer your questions, and hear your ideas. Join me on [GitHub Discussions](https://github.com/ezpie1/lambda-official/discussions) or drop a comment below!
Together, we can create a social media platform that truly prioritizes privacy and well-being. Thanks a lot! | ezpieco |
1,875,543 | Database Transactions : Basic Concepts | The concept of transaction provides a mechanism for describing logical units of database processing,... | 27,868 | 2024-06-26T11:18:01 | https://dev.to/aharmaz/database-transactions-basic-concepts-2gl2 | database, concurrency, performance, backend | The concept of transaction provides a mechanism for describing logical units of database processing, there are a lot of systems with large databases and hundreds of concurrent users executing database transactions, examples of such systems include airline reservation, banking, supermarket checkout and many others.
**What is a Transaction**
A transaction includes one or more database access operations forming a single unit of business work that either should be completed in its entirety or not done at all
If all the operations of a transaction are executed successfully, the transaction will be committed and the changes mades by its operations are going to be kept and persisted on the target database, on the other hand, if any operation fails the database will be rolled back to its initial state as if there was no execution of the transaction.
If the database operations in a transaction do not update the database but only retrieve data, the transaction is called a read-only transaction, otherwise it is known as read-write transaction
You may wonder about how a transaction would look like in real life, in fact a transaction can either be specified in a higher level language like SQL or can be embedded within an application program.
When specifying a transaction in SQL it is not mandatory to start it with the BEGIN or START statement, no matter what is the value of the auto commit option of the underlying database management system, however whenever we want to commit or rollback the transaction we must specify the COMMIT and ROLLBACK keywords for setting a clear boundaries to the transaction and preventing any confusion about that, here is an example :
When choosing to embed transaction within application programs, most of the cases we will benefit from an abstract management of the lifecycle related transactions, including committing and rollbacking, here is an example of a transaction in Spring Boot application :
**Desirable Properties of a Transaction**
For a safe transaction processing, transactions should have 4 properties called ACID properties :
*Atomicity*
A transaction is unbreakable, it is an atomic unit of processing, Either all its operations are reflected properly on the database, or none are, it is the responsibility of the recovery subsystem of a DBMS to ensure the atomicity. If a transaction fails to complete for some reason, such as a system crash in the midst of execution, the recovery technique must undo any effects of the transaction on the database. On the other hand, write operations of a committed transaction must be eventually written to disk
*Consistency*
A transaction should be consistency preserving, meaning that should take the database from its initial state into a state respecting integrity constraints, this property is the responsibility of both the programmer would should not perform wrong operations in the transaction, nothing will prevent him from deleting the entire database in his transaction.
*Isolation*
A transaction should appear as though it is being executed in isolation from other transactions, even though many transactions are execut- ing concurrently, this property is enforced by the concurrency control subsystem of a DBMS.
*Durability*
The changes applied to the database by a committed transaction must persist in the database, and must not be lost because of any failure. This is the responsibility of the recovery subsystem.

1,891,082 | Use AWS Generative AI CDK constructs to speed up app development | Assemble and deploy the infrastructure for a RAG solution using AWS CDK for Python In this blog,... | 0 | 2024-06-26T11:13:54 | https://community.aws/content/2i0FzzLt9YblQmerQW0eCuydsja | python, infrastructureascode, machinelearning, tutorial | > Assemble and deploy the infrastructure for a RAG solution using AWS CDK for Python
In this blog, we will use the AWS Generative AI Constructs Library to deploy a complete RAG application composed of the following components:
- [Knowledge Bases for Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base.html): This is the foundation for the RAG solution.
- [OpenSearch Serverless](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/serverless.html) collection: It supports the vector search collection type that provides similarity search capability.
- An S3 bucket: This will act as [the data source](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base-ds.html) for the Knowledge Base.
- **AWS Lambda function** (written in Python) along with an **API Gateway** that uses the [RetrieveAndGenerate API](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_agent-runtime_RetrieveAndGenerate.html) to query the knowledge base and generate responses from the information it retrieves.
## Introduction
[AWS Cloud Development Kit (AWS CDK)](https://docs.aws.amazon.com/cdk/v2/guide/home.html) is an open-source software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. You can use any of these supported programming languages (TypeScript, JavaScript, Python, Java, C#/.Net, and Go) to define reusable cloud components known as *constructs*, that represent one or more AWS CloudFormation resources and their configuration.
Constructs from the AWS Construct Library are [categorized into three levels](https://docs.aws.amazon.com/cdk/v2/guide/constructs.html#constructs_lib) with each level offers an increasing level of abstraction.
- **L1 constructs** are the lowest-level construct and offer no abstraction. Each L1 construct maps directly to a single AWS CloudFormation resource.
- **L2 constructs** provide a higher-level abstraction along with helper methods for most resources that make it simpler to define resources.
- **L3 constructs**, also known as patterns, are the highest-level of abstraction, and are used to create entire AWS architectures for particular use cases in your application.
[Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/what-is-bedrock.html) is a fully managed service that makes high-performing foundation models (FMs) from leading AI startups and Amazon available for your use through a unified API. As far as AWS CDK is concerned, [Bedrock does not support L2 constructs](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_bedrock-readme.html) yet.
[AWS Generative AI Constructs Library](https://github.com/awslabs/generative-ai-cdk-constructs) is an open-source extension of the AWS Cloud Development Kit (AWS CDK) and fills the gap by providing L2 and L3 constructs to help developers build generative AI solutions using pattern-based definitions for their architecture.
Let's get started!
## Prerequisites
Make sure to have the following setup and configured: [AWS CDK](https://docs.aws.amazon.com/cdk/v2/guide/getting_started.html), Python, Docker.
Also, [configure and set up Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/setting-up.html), including requesting access to the Foundation Model(s). The application uses [Amazon Titan Text Embeddings model](https://docs.aws.amazon.com/bedrock/latest/userguide/titan-embedding-models.html) along with the [Anthropic Claude 3 Sonnet](https://docs.aws.amazon.com/bedrock/latest/userguide/model-ids.html) as the LLM.
## Deploy the CDK stack
Start by cloning the GitHub repo:
```bash
git clone https://github.com/abhirockzz/aws-cdk-generative-ai-rag
cd aws-cdk-generative-ai-rag
```
Make sure to use the **docs** folder to add the documents (PDFs etc.) that you want to be used as a source for QnA. These will be automatically uploaded to a S3 bucket that will serve as the data source for Knowledge Base. Here is the [list of document types](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base-ds.html) supported by Knowledge Base.
Activate virtual env and install dependencies:
```
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```
Deploy the stack:
```bash
cdk deploy
```
It might take at least five minutes for the deployment to complete. Once done, verify the CloudFormation stack in the AWS Console.
Navigate to the Knowledge Base and [sync the data source](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base-ingest.html) with the OpenSearch Serverless vector index.
## Start asking questions
For QnA, you can use the API Gateway endpoint. Send queries via a POST request - make sure you add `/query` at the end of the API Gateway URL. I had uploaded the [Amazon 2022 shareholder document](https://s2.q4cdn.com/299287126/files/doc_financials/2023/ar/2022-Shareholder-Letter.pdf) and asked the following question:
*"What is Amazon doing in the field of generative AI?"*
```bash
export APIGW_URL=<enter URL>
curl -X POST -d 'What is Amazon doing in the field of generative AI?' $APIGW_URL/query
```
Below is the result returned by the Lambda function based on response from `RetrieveAndGenerate` API:
```json
{
"question": "what is amazon doing in the field of generative AI?",
"response": "Amazon is investing heavily in Large Language Models (LLMs) and Generative AI. The company believes that Generative AI will transform and improve virtually every customer experience across its businesses. Amazon has been working on developing its own LLMs for a while now. Amazon Web Services (AWS) is democratizing Generative AI technology by offering price-performant machine learning chips like Trainium and Inferentia, so that companies of all sizes can afford to train and run their LLMs in production. AWS also enables companies to choose from various LLMs and build applications with AWS's security, privacy and other features. One example is AWS's CodeWhisperer, which uses Generative AI to generate code suggestions in real time, boosting developer productivity."
}
```
## Delete the stack
Once you are done, don't forget to delete the stack, which in turn will delete all the components:
```bash
cdk destroy
```
## CDK stack code walk through
Here is a quick walkthrough of the different components in the stack - [refer to the complete code here](https://github.com/abhirockzz/aws-cdk-generative-ai-rag/blob/master/rag/rag_stack.py).
The Knowledge Base along with the S3 bucket, uploaded document(s), and the data source configuration:
```python
kb = bedrock.KnowledgeBase(self, 'DocKnowledgeBase',
embeddings_model= bedrock.BedrockFoundationModel.TITAN_EMBED_TEXT_V1,
)
documentBucket = s3.Bucket(self, 'DocumentBucket')
deployment = s3deploy.BucketDeployment(self, "DeployDocuments",
sources=[s3deploy.Source.asset("docs")],
destination_bucket=documentBucket
)
bedrock.S3DataSource(self, 'KBS3DataSource',
bucket= deployment.deployed_bucket,
knowledge_base=kb,
data_source_name='documents',
chunking_strategy= bedrock.ChunkingStrategy.FIXED_SIZE,
max_tokens=500,
overlap_percentage=20
)
```
The Lambda function (along with necessary IAM policies) that invokes the RetrieveAndGenerate API - [refer to the code here](https://github.com/abhirockzz/aws-cdk-generative-ai-rag/blob/master/lambda/app.py).
```python
kbQueryLambdaFunction = _lambda.Function(
self, 'KBQueryFunction',
runtime=_lambda.Runtime.PYTHON_3_12,
code=_lambda.Code.from_asset('lambda'),
handler='app.handler',
environment={
'KB_ID': kb.knowledge_base_id,
'KB_MODEL_ARN': 'arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-3-sonnet-20240229-v1:0',
},
timeout=Duration.seconds(15)
)
kbArn = f'arn:aws:bedrock:{Stack.of(self).region}:{Stack.of(self).account}:knowledge-base/{kb.knowledge_base_id}'
# Create an IAM policy statement
policy_statement = iam.PolicyStatement(
actions=[

In 2011, we developed custom backup scripts that efficiently handled backups for our client's web projects. These scripts served us well for many years, storing backups in both our storage and external repositories as needed. However, as our software ecosystem grew and diversified, our scripts fell short, lacking support for new technologies like Redis and MySQL/PostgreSQL. The scripts also became cumbersome, with no monitoring system other than email alerts.
Our once compact scripts evolved into a complex and unmanageable system. Updating these scripts for different customers became challenging, particularly when they used customized versions. By early last year, we realized we needed a more modern solution.
In this article, we will explain all the difficulties we faced while developing [nxs-backup](https://nxs-backup.io/?utm_source=devto&utm_medium=article&utm_campaign=26.06.2024&utm_content=backup) and share our experiences and challenges. You can also test the tool on your project and share your experience, we would be very interested to hear from you. Now, let's get started!
We listed our requirements for a new system:
- Backup data of the most commonly used software: (Files: discrete and incremental; MySQL; PostgreSQL; MongoDB; Redis);
- Store backups in popular repositories: (FTP; SSH; SMB; NFS; WebDAV; S3);
- Receive alerts in case of problems during the backup process;
- Have a unified configuration file to manage backups centrally;
- Add support for new software by connecting external modules;
- Specify extra options for collecting dumps;
- Be able to restore backups with standard tools;
- Ease of initial configuration.
All these requirements were listed based on our needs about 5 years ago. Unfortunately, not all of them were released.
We looked at open-source solutions that already existed even before creating our first version of nxs-backup. But they all had their flaws. For example, Bacula is overloaded with unnecessary functions for us, initial configuration is — rather a laborious occupation due to a lot of manual work (for example, for writing/searching scripts of database backups), and to recover copies need to use special utilities, etc.
No surprise that we faced the same problem while having an idea of rewriting our tool. The possibility of the fact that in four years something has changed and new tools have appeared online was not that high, but still.
We studied a couple of new tools that were not considered before. But, as discussed earlier, these also did not suit us. Because they did not fully meet our requirements.
We finally came to two important conclusions:
1. None of the existing solutions was fully suitable for us;
2. It seems we’ve had enough experience and craziness to write our solution for the first time. And we basically could do that again.
So that’s what we did.
Before exploring the new version, let’s take a look at what we had before and why it was not enough for us.
The old version supported such DBs as MySQL, PostgreSQL, Redis, MongoDB, discrete and incremental copying of files, multiple remote storages (S3; SMB; NFS; FTP; SSH; WebDAV) and had such features as backup rotation, logging, e-mail notifications, and external modules.
Now, more on what we were concerned about.
**Run a binary file without restarting the source file on any Linux**
Over time, the list of systems we work with has grown considerably. Now we serve projects that use other than standard deb and rpm compatible distributions such as Arch, Suse, Alt, etc.
Recent systems had difficulty running nxs-backup because we only collected deb and rpm packages and supported a limited list of system versions. Somewhere we re-plucked the whole package, somewhere just binary, somewhere we just had to run the source code.
Working with the old version was very inconvenient for engineers, due to the need to work with the source. Not to mention that installation and updating in such mode take more time. Instead of setting up 10 servers per hour, you only had to spend an hour on one server.
We’ve known for a long time that it’s much better when you have a binary without system dependencies that you can run on any distribution and not experience problems with different versions of libraries and architectural differences in systems. We wanted this tool to be the same.
**Minimize docker image with nxs-backup and support ENV in configuration files**
Lately, so many projects are working in a containerized environment. These projects also require backups, and we run nxs-backup in containers. For containerized environments, it’s very important to minimize the image size and be able to work with environment variables.
The old version did not provide an opportunity to work with environment variables. The main problem was that passwords had to be stored directly in the config. Because of this, instead of a set of variables containing only passwords, you have to put the whole config into a variable. Editing large environment variables requires more concentration from engineers and makes troubleshooting a bit more difficult.
Also, when working with the old version, we had to use an already large Debian image, in which we needed to add several libraries and applications for correct backups.
Even using a slim version of the image we got a minimum size of ~250Mb, which is quite a lot for one small utility. In some cases, this affected the starting process of the collection because of how long the image was pulled onto the node. We wanted to get an image that wasn’t larger than 50 MB.
**Work with remote storage without fuse**
Another problem for container environments is using fuse to mount remote storage.
While you are running backups on the host, this is still acceptable: you have installed the right packages and enabled fuse in the kernel, and now it works.
Things get interesting when you need fuse in a container. Without an upgrade of privileges with direct access to the core of the host system, the problem is not solved, and this is a significant decrease in the security level.
This needs to be coordinated, not all customers agree to weaken security policies. That’s why we had to make a terrible amount of workarounds we don’t even want to recall. Furthermore, the additional layer increases the probability of failure and requires additional monitoring of the state of the mounted resources. It is safer and more stable to work with remote storage using their API directly.
**Monitoring status and sending notifications not only to email**
Today, teams are less and less using email in their daily work. It is understandable because it’s much faster to discuss the issue in a group chat or on a group call. Telegram, Slack, Mattermost, MS Teams, and other similar products are widely distributed by that.
We also have a bot, which sends various alerts and notifies us about them. And of course, we’d like to see reports of backups crashing in the workspace like Telegram, not email, among hundreds of other emails. By the way, some customers also want to see information about failures in their Slack or other messenger.
In addition, you long want to be able to track the status and see the details of the work in real-time. To do this, you need to change the format of the application, turning it into a demon.
**Insufficient performance**
Another acute pain was insufficient performance in certain scenarios.
One of the clients has a huge file dump of almost a terabyte and all of it is small files — text, pictures, etc. We’re collecting incremental copies of this stuff, and have the following problem — a yearly copy takes THREE days. Yeah, well, the old version just can’t digest that volume in less than a day.
Given the circumstances, we are, in fact, unable to recover data on a specific date, which we do not like at all.
Initially, we implemented our backup solution in Python due to its simplicity and flexibility. However, as demands grew, the Python-based solution became inadequate. After a thorough discussion, we decided to rewrite the system in Go for several reasons:
1. Compilation and Dependencies: Go's AOT compiler produces a universal, dependency-free binary, simplifying deployment across different systems;
2. Performance: Go's inherent multithreading capabilities promised better performance;
3. Team Expertise: We had more developers experienced in Go than in Python.
**Finding a solution**
All of the above problems, to a greater or lesser extent, caused quite a palpable pain to the IT department, causing them to spend precious time on certainly important things, but these costs could have been avoided. Moreover, in certain situations certain risks were created for business owners — the probability of being without data for a certain day, although extremely low, but not zero. We refused to accept the state of affairs.
**_Nxs-backup 3.0_**
The result of our work was a new version of nxs-backup v 3.0 which recently had an update to [v3.8.0](https://nxs-backup.io/documentation/stable/1-1-overview/)
Key features of the new version:
- Implement the corresponding interfaces of all storage facilities and all types of backups. Jobs and storage are initialized at the start, and not while the work is running;
- Work with remote storage via API. For this, we use various libraries;
- Use environment variables in configs, thanks to the go-nxs-appctx mini-application framework that we use in our projects;
- Send log events via hooks. You can configure different levels and receive only errors or events of the desired level;
- Specify not only the period of time for backup, but also a specific number of backups;
- Backups now simply run on your Linux starting with the 2.6 kernel. This made it much easier to work with non-standard systems and faster to build Docker images. The image itself was reduced to 23 MB (with additional MySQL and SQL clients included);
- Ability to collect, export, and save different metrics in Prometheus-compatible format.
- Limiting resource consumption for local disk rate and remote storage.
We have tried to keep most of the configurations and application logic, but some changes are present. All of them are related to the optimization and correction of defects in the previous version.
For example, we put the connection parameters to the remote repositories into the basic configuration so that we don’t prescribe them for different types of backups each time.
Below is an example of the basic configuration for backups. It contains general settings such as notification channels, remote storage, logging, and job list. This is the basic main config with mail notification, we strongly recommend using email notifications as the default method. If you need more features you can see the reference in the [documentation](https://nxs-backup.io/?utm_source=devto&utm_medium=article&utm_campaign=26.06.2024&utm_content=backup).

**A few words about pitfalls**
We expected to face certain challenges. It would be foolish to think otherwise. But two problems caused the strongest butthurt.
**Memory leak or non-optimal algorithm**
Even in the previous version of nxs-backup we used our own implementation of file archiving. The logic of this solution was to try to avoid using external tools to create backups, and working with files was the easiest step possible.
In practice, the solution proved to be workable, although not particularly effective on a large number of files, as could be seen from the tests. Back then we wrote it off to Python’s specifics and hoped to see a significant difference when we switched to Go.
When we finally got to the load testing of the new version, we got disappointing results. There were no performance gains and memory consumption was even higher than before. We were looking for a solution. Read a lot of articles and research on this topic, but they all said that the use of «filepath.Walk» and «filepath.WalkDir» is the best option. The performance of these methods only increases with the release of new versions of the language.
In an attempt to optimize memory consumption, we have even made mistakes in creating incremental copies. By the way, broken options were actually more effective. For obvious reasons, we did not use them.
Eventually, it all stuck to the number of files to be processed. We tested 10 million. Garbage Collector does not seem to be able to clear this amount of generated variables.
Eventually, realizing that we could bury too much time here, we decided to abandon our implementation in favor of a time-tested and truly effective solution — GNU tar.
We may come back to the idea of self-implementation later when we come up with a more efficient solution to handle tens of millions of files.
**Such a different ftp**
Another problem came up when working with ftp. It turned out that different servers behave differently for the same requests.
And it’s a really serious problem when for the same request you get either a normal answer, or an error that doesn’t seem to have anything to do with your request, or you don’t get a bug when you expect it.
So, we had to give up using the library “prasad83/goftp” in favor of a simpler “jlaffaye/ftp”, because the first could not work correctly with the Selectel server. The error was that when connecting, the first one tried to get the list of files in the working directory and got the error of access rights to the higher directory. With “jlaffaye/ftp” such a problem does not exist, because it is simpler and does not send any requests to the server.
The next problem was a disconnect when there were no requests. Not all servers behave this way, but some do. So we had to check before each request whether the connector had fallen off and reconnected.
The cherry on top was the problem of getting files from the server, or to be clear, an attempt to get a file that did not exist. Some servers give an error when trying to access such a file, others return a valid io.Reader interface object that can even be read, only you get an empty cut of bytes.
All of these situations have been discovered empirically and have to be handled on their own side.
**_Conclusions_**
Most importantly, we fixed the problems of the old version, the things that affected the work of engineers and created certain risks for business.
We still have unrealized “wants” from the last version, such as:
- Backup encryption;
- Restore from backup using nxs-backup tools;
- Web interface to manage the list of jobs and their settings.
This list is now extended with new ones:
- Own job scheduler. Use customized settings instead of system crones;
- New backup types (Clickhouse, Elastic, lvm, etc).
And, of course, we will be happy to know the community’s opinion. What other development opportunities do you see? What options would you add?

Customs Procedure Codes (CPCs) are here to help. Created by HM Revenue & Customs (HMRC), these codes are designed to simplify and streamline the import and export process, ensuring smoother transactions for traders.
## Understanding Customs Procedure Codes (CPCs)
CPCs are unique identifiers used in international trade to help customs understand the journey and status of goods entering or leaving a country. They serve as guidelines for customs officials, dictating the necessary actions, fee assessments, and tax implications for the goods.
## Why CPCs Matter:
Guidance for Customs: CPCs provide clear instructions on handling goods, whether they’re imported, exported, or moved between customs zones.
Financial Implications: They determine the applicable fees and taxes, helping manage the financial aspects of trade.
Diverse Applications: CPCs cover various scenarios, from temporary imports for processing to permanent exports, ensuring compliance with all regulations.
## Components of CPCs:
A typical CPC consists of 7-8 digits, each segment offering specific information about the goods. The initial digits indicate the type of customs procedure, while the latter part provides detailed handling instructions.
## Examples of CPCs:
05: Special processing imports.
10: Permanent exports.
21: Temporary exports for processing.
40: Regular imports for use.
42: Imports with tax exemptions.

1,901,167 | Python, Classes and Objects | Classes and Objects in Python In Python, classes and objects are fundamental to... | 0 | 2024-06-26T11:05:25 | https://dev.to/harshm03/python-classes-and-objects-4d53 | python, programming, beginners, tutorial | ## Classes and Objects in Python
In Python, classes and objects are fundamental to object-oriented programming (OOP), offering a way to structure code into reusable components and define behaviors.
### Defining Classes
#### Syntax for Defining a Class
To define a class in Python, use the `class` keyword followed by the class name and a colon `:`. Inside the class block, you define attributes (data) and methods (functions).
```python
class MyClass:
# Class body
pass # Placeholder for class definition
```
In this example:
- `MyClass` is the name of the class.
- The `pass` statement is a placeholder indicating that the class body is currently empty.
This syntax sets up the blueprint for creating instances (objects) of the class `MyClass`, which can then possess attributes and methods defined within the class.
### Attributes in Python Classes
Attributes in Python classes are used to store data associated with instances (objects) of the class. They can be broadly categorized into instance attributes and class attributes, each serving distinct purposes within the class.
#### Instance Attributes
Instance attributes are specific to each instance of a class. They are defined within the class's methods, especially within the `__init__` method, and are accessed using the `self` keyword.
##### Syntax for Instance Attributes
```python
class MyClass:
def __init__(self, name, age):
self.name = name # Instance attribute
self.age = age # Instance attribute
```
In this example:
- `name` and `age` are instance attributes.
- They are initialized when an instance of `MyClass` is created, and each instance (`self`) holds its own values for these attributes.
#### Class Attributes
Class attributes are shared among all instances of a class. They are defined at the class level outside of any instance methods, typically before the `__init__` method, and are accessed using the class name or `self` within instance methods.
##### Syntax for Class Attributes
```python
class MyClass:
class_attribute = "Class Attribute Value"
def __init__(self, instance_attribute):
self.instance_attribute = instance_attribute
```
In this example:
- `class_attribute` is a class attribute shared by all instances of `MyClass`.
- It is accessed using `MyClass.class_attribute` or `self.class_attribute` within instance methods.
### Static Properties
In Python, there isn't a direct concept of "static properties" like in some other languages. However, you can achieve similar behavior using class attributes and static methods. Class attributes act as static properties that are shared among all instances of a class.
#### Example of Using Class Attributes as Static Properties
```python
class MyClass:
static_property = "Static Property Value"
@staticmethod
def get_static_property():
return MyClass.static_property
@staticmethod
def set_static_property(value):
MyClass.static_property = value
```
In this example:
- `static_property` is a class attribute acting as a static property.
- `get_static_property()` and `set_static_property(value)` are static methods used to get and set the value of `static_property`.
### Methods in Python Classes
Methods in Python classes are functions defined within the class and are used to define behaviors associated with instances (objects) of the class. They can be categorized into instance methods, class methods, and static methods, each serving different purposes within the class.
#### Instance Methods
Instance methods are the most common type of methods in Python classes. They operate on instances of the class and have access to instance attributes through the `self` parameter.
##### Syntax for Instance Methods
```python
class MyClass:
def __init__(self, name):
self.name = name
def instance_method(self):
return f"Hello, my name is {self.name}"
```
In this example:
- `instance_method` is an instance method defined within `MyClass`.
- It takes `self` as the first parameter, allowing access to instance attributes like `self.name`.
#### Class Methods
Class methods operate on the class itself rather than instances. They are defined using the `@classmethod` decorator and take `cls` as the first parameter, allowing access to class-level attributes.
##### Syntax for Class Methods
```python
class MyClass:
class_attribute = "Class Attribute Value"
@classmethod
def class_method(cls):
return f"Class attribute value: {cls.class_attribute}"
```
In this example:
- `class_method` is a class method defined using `@classmethod`.
- It takes `cls` as the first parameter, allowing access to `MyClass`'s class attributes like `cls.class_attribute`.
#### Static Methods
Static methods do not operate on instance or class state. They are defined using the `@staticmethod` decorator and do not take `self` or `cls` as parameters. They are primarily used for utility functions related to the class.
##### Syntax for Static Methods
```python
class MyClass:
@staticmethod
def static_method():
return "This is a static method"
```
In this example:
- `static_method` is a static method defined using `@staticmethod`.
- It does not take `self` or `cls` as parameters and operates independently of instance or class state.
### Example of Using Methods
```python
class MyClass:
def __init__(self, name):
self.name = name
def instance_method(self):
return f"Hello, my name is {self.name}"
@classmethod
def class_method(cls):
return f"Class method called"
@staticmethod
def static_method():
return "Static method called"
```
In this example:
- `MyClass` defines an `instance_method`, `class_method`, and `static_method`.
- Each method serves a distinct purpose: `instance_method` interacts with instance-specific data, `class_method` interacts with class-level data, and `static_method` operates independently of instance or class state.
### Creating Objects in Python
Creating objects in Python involves instantiating (creating instances of) classes. Each object, or instance, can be initialized with or without using a constructor method (`__init__` method) to define its initial state.
#### Instantiating Objects from Classes
To create an object from a class in Python, you call the class name followed by parentheses `()`. This invokes the class constructor to create a new instance (object) of that class.
##### Example of Creating Objects Without Constructors
```python
class MyClass:
name = "Default"
# Creating objects (instances) of MyClass
obj1 = MyClass()
obj2 = MyClass()
# Accessing class property
print(obj1.name) # Output: Default
print(obj2.name) # Output: Default
```
In this example:
- `MyClass` is a class with a `name` class attribute.
- `obj1` and `obj2` are instances (objects) of `MyClass`, each inheriting the `name` attribute from the class.
### Constructor and Initializing Objects with Constructors (`__init__` Method)
In Python, the constructor method (`__init__`) is used to initialize objects when they are created from a class. It is automatically called every time a new instance (object) of the class is instantiated.
#### Constructor (`__init__` Method)
The `__init__` method is a special method in Python classes that initializes (sets up) an object's initial state. It is commonly used to initialize instance attributes (properties) of the object.
##### Syntax of `__init__` Method
```python
class ClassName:
def __init__(self, parameter1, parameter2, ...):
self.attribute1 = parameter1
self.attribute2 = parameter2
# Additional initialization code
```
- `self`: Represents the instance of the class. It is used to access and modify instance attributes within the class.
- `parameter1, parameter2, ...`: Parameters passed to the constructor when creating an object.
- `self.attribute1, self.attribute2`: Instance attributes initialized with values from the constructor parameters.
#### Initializing Objects with Constructors
When an object is created from a class, Python automatically calls the `__init__` method to initialize the object's state.
##### Example of Initializing Objects with Constructors
```python
class Product:
def __init__(self, name, price):
self.name = name
self.price = price
# Creating objects (instances) of Product
product1 = Product("Laptop", 1200)
product2 = Product("Mouse", 30)
# Accessing object properties
print(product1.name, product1.price) # Output: Laptop 1200
print(product2.name, product2.price) # Output: Mouse 30
```
In this example:
- `Product` is a class with an `__init__` method that takes `name` and `price` parameters.
- `product1` and `product2` are instances (objects) of `Product`, each initialized with specific `name` and `price` values.
- The `__init__` method initializes `self.name` and `self.price` attributes for each instance based on the parameters passed during object creation.
### Accessing and Modifying Instance Variables and Methods in Python
In Python object-oriented programming, accessing and modifying instance variables (attributes) and methods are fundamental operations when working with classes and objects. Instance variables store data unique to each instance (object) of a class, while methods define behaviors or actions that instances can perform.
#### Accessing Instance Variables
Instance variables are accessed using dot notation (`object.variable_name`). They represent the state or properties of each individual object.
##### Example of Accessing Instance Variables
```python
class Car:
def __init__(self, make, model):
self.make = make
self.model = model
# Creating an instance (object) of Car
my_car = Car("Toyota", "Camry")
# Accessing instance variables
print(my_car.make) # Output: Toyota
print(my_car.model) # Output: Camry
```
In this example:
- `make` and `model` are instance variables of the `Car` class.
- `my_car.make` and `my_car.model` access the values of these variables for the `my_car` instance.
#### Modifying Instance Variables
Instance variables can be modified directly using assignment (`object.variable_name = new_value`).
##### Example of Modifying Instance Variables
```python
class Car:
def __init__(self, make, model):
self.make = make
self.model = model
# Creating an instance (object) of Car
my_car = Car("Toyota", "Camry")
# Modifying instance variables
my_car.make = "Honda"
my_car.model = "Accord"
# Accessing modified instance variables
print(my_car.make) # Output: Honda
print(my_car.model) # Output: Accord
```
In this example:
- After creating `my_car` instance with initial values "Toyota" and "Camry", we modify `make` to "Honda" and `model` to "Accord".
- Subsequent accesses (`print` statements) show the updated values of `make` and `model`.
#### Accessing and Modifying Methods
Methods in Python classes define behaviors that instances can perform. They can access and modify instance variables through the `self` parameter.
##### Example of Accessing and Modifying Methods
```python
class Car:
def __init__(self, make, model):
self.make = make
self.model = model
def display_info(self):
print(f"Car make: {self.make}, model: {self.model}")
def update_model(self, new_model):
self.model = new_model
# Creating an instance (object) of Car
my_car = Car("Toyota", "Camry")
# Accessing methods
my_car.display_info() # Output: Car make: Toyota, model: Camry
# Modifying instance variable through method
my_car.update_model("Corolla")
# Displaying updated information
my_car.display_info() # Output: Car make: Toyota, model: Corolla
```
In this example:
- The `Car` class defines `display_info()` to print car make and model, and `update_model(new_model)` to modify the `model` instance variable.
- `my_car.display_info()` displays initial values "Toyota" and "Camry".
- `my_car.update_model("Corolla")` modifies `model` to "Corolla", reflected in subsequent `display_info()` call.
### Accessing and Modifying Class Variables and Methods in Python
In Python, class variables and methods provide functionality and data that are shared across all instances of a class. They allow for centralized data management and behaviors that are not tied to any specific instance but rather to the class itself. Here's a comprehensive overview of accessing and modifying class variables, class methods, and static methods in Python.
#### Class Variables
Class variables are variables that are shared among all instances of a class. They are defined within the class but outside of any instance method.
##### Example of Class Variables
```python
class Car:
num_wheels = 4 # Class variable
def __init__(self, make, model):
self.make = make
self.model = model
# Accessing class variable through class
print(Car.num_wheels) # Output: 4
# Accessing class variable through instance
my_car = Car("Toyota", "Camry")
print(my_car.num_wheels) # Output: 4
```
In this example:
- `num_wheels` is a class variable defined within the `Car` class.
- The `__init__` method is the constructor, initializing instance variables `make` and `model`.
- Both `Car.num_wheels` and `my_car.num_wheels` access the same class variable.
#### Modifying Class Variables
Class variables can be modified using either the class name or any instance of the class.
##### Example of Modifying Class Variables
```python
class Car:
num_wheels = 4 # Class variable
def __init__(self, make, model):
self.make = make
self.model = model
# Modifying class variable through class
Car.num_wheels = 6
print(Car.num_wheels) # Output: 6
# Modifying class variable through instance
my_car = Car("Toyota", "Camry")
my_car.num_wheels = 5
print(my_car.num_wheels) # Output: 5
print(Car.num_wheels) # Output: 6 (class variable remains unchanged)
```
In this example:
- `Car.num_wheels` is modified to 6 directly.
- `my_car.num_wheels` is modified to 5, creating an instance variable that shadows the class variable for that instance only.
#### Class Methods
Class methods are methods that are bound to the class rather than its instances. They can access and modify class variables.
##### Example of Class Methods
```python
class Car:
num_wheels = 4 # Class variable
def __init__(self, make, model):
self.make = make
self.model = model
@classmethod
def update_wheels(cls, num):
cls.num_wheels = num
# Calling class method through class
Car.update_wheels(6)
print(Car.num_wheels) # Output: 6
# Calling class method through instance
my_car = Car("Toyota", "Camry")
my_car.update_wheels(5)
print(my_car.num_wheels) # Output: 5
print(Car.num_wheels) # Output: 5 (class variable updated)
```
In this example:
- `update_wheels(cls, num)` is a class method defined with `@classmethod`.
- Both `Car.update_wheels(6)` and `my_car.update_wheels(5)` modify the `num_wheels` class variable.
#### Static Methods
Static methods in Python are methods that do not operate on instance or class state. They are defined using `@staticmethod` and can be accessed through both the class and its instances.
##### Example of Static Methods
```python
class Car:
def __init__(self, make, model):
self.make = make
self.model = model
@staticmethod
def make_sound():
print("Vroom!")
# Calling static method through class
Car.make_sound() # Output: Vroom!
# Calling static method through instance
my_car = Car("Toyota", "Camry")
my_car.make_sound() # Output: Vroom!
```
In this example:
- `make_sound()` is a static method defined with `@staticmethod`.
- It does not require `self` or `cls` parameters and can be called using both the class name (`Car.make_sound()`) and instance (`my_car.make_sound()`).
### Encapsulation in Python
Encapsulation is one of the fundamental principles of object-oriented programming (OOP) that bundles data (attributes) and methods (functions) into a single unit called a class. It allows you to restrict access to certain components of the object, promoting data hiding and abstraction.
#### Encapsulation and Data Hiding
Encapsulation helps in achieving data hiding, which means that the internal state of an object is hidden from the outside world. Only the object itself can directly interact with its internal state. This prevents external code from directly accessing or modifying sensitive data, promoting better security and maintainability of code.
#### Using Private and Protected Access Specifiers
In Python, encapsulation and access control are managed through naming conventions rather than strict access specifiers. However, Python provides conventions to indicate the visibility of attributes and methods:
1. **Private Members**: Attributes and methods that are intended to be private are prefixed with double underscores (`__`). Python uses name mangling to make these attributes and methods harder to access from outside the class.
Example:
```python
class MyClass:
def __init__(self):
self.__private_attr = 10
def __private_method(self):
return "This is a private method"
obj = MyClass()
# Accessing private attribute (not recommended)
# print(obj.__private_attr) # This would raise an AttributeError
# Accessing private method (not recommended)
# print(obj.__private_method()) # This would raise an AttributeError
```
Note: Although Python allows accessing private members in a roundabout way (`obj._MyClass__private_attr`), it's generally discouraged to do so to maintain encapsulation.
2. **Protected Members**: Attributes and methods that are intended to be protected are prefixed with a single underscore (`_`). This indicates to developers that these members are not intended for use outside the class, but there is no strict enforcement by the Python interpreter.
Example:
```python
class MyClass:
def __init__(self):
self._protected_attr = 20
def _protected_method(self):
return "This is a protected method"
obj = MyClass()
# Accessing protected attribute
print(obj._protected_attr) # Output: 20
# Accessing protected method
print(obj._protected_method()) # Output: This is a protected method
```
While these attributes and methods can be accessed directly, their leading underscore signals to other developers that they are part of the class's implementation and should be treated as protected.
### Inheritance in Python
Inheritance is a key concept in object-oriented programming (OOP) that allows a new class (derived class) to inherit attributes and methods from an existing class (base class). This promotes code reuse and allows for hierarchical relationships between classes.
#### Extending Classes: Base Class and Derived Class
In Python, inheritance is defined using the syntax `class DerivedClassName(BaseClassName):`, where `DerivedClassName` is the new class inheriting from `BaseClassName`. The derived class inherits all attributes and methods from the base class unless explicitly overridden.
##### Example of Inheritance
```python
class Animal:
def __init__(self, species):
self.species = species
def make_sound(self):
pass # Placeholder method
class Dog(Animal):
def __init__(self, name):
super().__init__("Dog") # Calling base class constructor
self.name = name
def make_sound(self):
return "Woof!"
# Creating instances of derived class
dog = Dog("Buddy")
print(dog.species) # Output: Dog (inherited from base class)
print(dog.make_sound()) # Output: Woof! (overridden method)
```
In this example:
- `Animal` is the base class with an attribute `species` and a method `make_sound`.
- `Dog` is the derived class inheriting from `Animal`.
- `super().__init__("Dog")` calls the constructor of the base class `Animal` and initializes the `species` attribute.
- `make_sound` method is overridden in `Dog` class to provide specific behavior for dogs.
#### Overriding Methods in Derived Classes
Derived classes can override methods from the base class to provide specialized implementations while retaining the same method signature. This allows flexibility in adapting behavior inherited from the base class.
##### Example of Method Overriding
```python
class Animal:
def make_sound(self):
return "Generic animal sound"
class Dog(Animal):
def make_sound(self):
return "Woof!"
class Cat(Animal):
def make_sound(self):
return "Meow!"
# Polymorphism: using overridden methods
dog = Dog()
cat = Cat()
print(dog.make_sound()) # Output: Woof!
print(cat.make_sound()) # Output: Meow!
```
In this example:
- Both `Dog` and `Cat` classes inherit from `Animal` class.
- They override the `make_sound` method to provide specific sounds for dogs and cats.
#### `super()` Function
The `super()` function in Python is used to call methods from the base class within the derived class. It allows accessing and invoking the methods and constructors of the base class, facilitating method overriding and cooperative multiple inheritance.
##### Example of Using `super()`
```python
class Animal:
def __init__(self, species):
self.species = species
def show_info(self):
print(f"I am a {self.species}")
class Dog(Animal):
def __init__(self, name):
super().__init__("Dog")
self.name = name
def show_info(self):
super().show_info()
print(f"My name is {self.name}")
# Using super() to call base class methods
dog = Dog("Buddy")
dog.show_info()
```
In this example:
- `Dog` class calls `super().__init__("Dog")` to invoke the constructor of the base class `Animal`.
- `super().show_info()` is used in `Dog` class to call the `show_info` method of the base class, followed by printing the dog's name.
Here's a comprehensive guide covering some of the important magic methods (special methods) in Python:
### Python Magic Methods Guide
#### Object Initialization and Representation
**`__init__`**
- Initializes an object when instantiated.
- **Syntax**: `def __init__(self, ...)`
```python
class MyClass:
def __init__(self, value):
self.value = value
obj = MyClass(10)
print(obj.value) # Output: 10
```
**`__str__`**
- Returns the informal or nicely printable string representation of an object.
- **Syntax**: `def __str__(self)`
```python
class MyClass:
def __init__(self, value):
self.value = value
def __str__(self):
return f"MyClass object with value: {self.value}"
obj = MyClass(10)
print(str(obj)) # Output: MyClass object with value: 10
```
**`__repr__`**
- Returns the official string representation of an object. Used for debugging and logging.
- **Syntax**: `def __repr__(self)`
```python
class MyClass:
def __init__(self, value):
self.value = value
def __repr__(self):
return f"MyClass({self.value})"
obj = MyClass(10)
print(repr(obj)) # Output: MyClass(10)
```
#### Comparison Operators
**`__eq__`**
- Checks equality between two objects.
- **Syntax**: `def __eq__(self, other)`
```python
class Point:
def __init__(self, x, y):
self.x = x
self.y = y
def __eq__(self, other):
return self.x == other.x and self.y == other.y
p1 = Point(1, 2)
p2 = Point(1, 2)
print(p1 == p2) # Output: True
```
**`__lt__`, `__le__`, `__gt__`, `__ge__`**
- Less than, less than or equal to, greater than, and greater than or equal to comparison methods respectively.
- **Syntax**: `def __lt__(self, other)`, `def __le__(self, other)`, `def __gt__(self, other)`, `def __ge__(self, other)`
```python
class Student:
def __init__(self, name, grade):
self.name = name
self.grade = grade
def __lt__(self, other):
return self.grade < other.grade
def __le__(self, other):
return self.grade <= other.grade
def __gt__(self, other):
return self.grade > other.grade
def __ge__(self, other):

num2 = Number(5)
print(num1 + num2) # Output: 15
```
#### Container Methods
**`__len__`**
- Returns the length of an object.
- **Syntax**: `def __len__(self)`
```python
class MyList:
def __init__(self, items):
self.items = items
def __len__(self):
return len(self.items)
my_list = MyList([1, 2, 3, 4])
print(len(my_list)) # Output: 4
```
**`__getitem__`**, `__setitem__`, `__delitem__`
- Getter, setter, and deleter methods for accessing and modifying items using index or key.
- **Syntax**: `def __getitem__(self, key)`, `def __setitem__(self, key, value)`, `def __delitem__(self, key)`
```python
class MyDict:
def __init__(self, items):
self.items = items
def __getitem__(self, key):
return self.items[key]
def __setitem__(self, key, value):
self.items[key] = value
def __delitem__(self, key):
del self.items[key]
my_dict = MyDict({'a': 1, 'b': 2})
print(my_dict['a']) # Output: 1
my_dict['c'] = 3
print(my_dict['c']) # Output: 3
del my_dict['b']
print(my_dict.items) # Output: {'a': 1, 'c': 3}
```
#### Callable Objects
**`__call__`**
- Enables the instance of a class to be called as a function.
- **Syntax**: `def __call__(self, *args, **kwargs)`
```python
class Multiplier:
def __init__(self, factor):
self.factor = factor
def __call__(self, x):
return self.factor * x
mul = Multiplier(5)
result = mul(10)
print(result) # Output: 50
```
### Type Conversion
- `__int__(self)`: Convert to an integer (`int()`).
- `__float__(self)`: Convert to a float (`float()`).
- `__complex__(self)`: Convert to a complex number (`complex()`).
- `__bytes__(self)`: Convert to a bytes object (`bytes()`).
- `__index__(self)`: Called for integer indexing (`obj[idx]`).
#### Example:
```python
class Number:
def __init__(self, value):
self.value = value
def __int__(self):
return int(self.value)
def __float__(self):
return float(self.value)
def __complex__(self):
return complex(self.value, 0)
def __bytes__(self):
return bytes(str(self.value), 'utf-8')
def __index__(self):
return int(self.value)
num = Number(42)
print(int(num)) # Output: 42
print(float(num)) # Output: 42.0
print(complex(num)) # Output: (42+0j)
print(bytes(num)) # Output: b'42'
print('{:x}'.format(num.__index__())) # Output: 2a
```
### Boolean Conversion
- `__bool__(self)`: Boolean value of the object (`bool()`).
#### Example:
```python
class Person:
def __init__(self, name):
self.name = name
def __bool__(self):
# Returns False if name is empty, True otherwise
return bool(self.name)
person1 = Person("Alice")
person2 = Person("")
print(bool(person1)) # Output: True
print(bool(person2)) # Output: False

1,901,150 | Idempotency in Computing: A Comprehensive Guide | In the realms of computer science and software engineering, certain concepts and principles play... | 0 | 2024-06-26T10:37:14 | https://dev.to/keploy/httpskeployiodocsconceptsreferenceglossaryidempotency-36np | webdev, javascript, beginners, tutorial |
In the realms of computer science and software engineering, certain concepts and principles play crucial roles in ensuring systems' robustness, reliability, and predictability. One such concept is idempotency, a term that, while seemingly esoteric, has profound implications in various areas, including web services, databases, and functional programming. This article delves into the definition, importance, and practical applications of [idempotency](https://keploy.io/docs/concepts/reference/glossary/idempotency/), aiming to provide a comprehensive understanding of its role in modern computing.
What is Idempotency?
Idempotency is a property of certain operations that denotes their ability to be applied multiple times without changing the result beyond the initial application. Formally, an operation fff is idempotent if, for all inputs xxx, applying fff to xxx multiple times yields the same result as applying fff once. Mathematically, this is represented as:
f(f(x))=f(x)f(f(x)) = f(x)f(f(x))=f(x)
This definition implies that no matter how many times the operation is executed, the outcome remains constant after the first application.
The Importance of Idempotency
The significance of idempotency in computing can be appreciated across various dimensions:
1. Reliability: Idempotent operations ensure that systems can handle retries gracefully. In distributed systems, where network failures and partial system failures are common, retrying operations without fearing unintended consequences is crucial.
2. Safety: In web services, making HTTP requests idempotent means that if a client sends the same request multiple times, the server's state remains unchanged after the first request. This is particularly important for operations like payment processing or resource creation.
3. Consistency: Idempotency helps maintain data consistency. For instance, in database operations, an idempotent transaction can be retried multiple times in the event of a failure, ensuring that the database remains in a consistent state.
4. Simplicity: Idempotent operations simplify error handling logic. Since the result of applying an operation multiple times does not change, developers can avoid complex checks and conditions in their code.
Idempotency in Web Services
Idempotency is a critical concept in the design of RESTful web services. The HTTP specification defines certain methods as idempotent:
• GET: This method is inherently idempotent, as it is used to retrieve resources without modifying them.
• PUT: Used to update or create resources, PUT requests are idempotent because applying the same update multiple times does not change the resource state beyond the initial application.
• DELETE: While logically idempotent (deleting a resource that is already deleted does not change the state), it can have side effects such as triggering notifications.
• HEAD and OPTIONS: These methods are also idempotent as they are used for metadata retrieval and preflight requests, respectively.
Implementing Idempotency
The implementation of idempotency depends on the context and specific requirements of the operation. Here are some common strategies:
1. Idempotency Keys: For operations like resource creation or transaction processing, clients can generate unique idempotency keys. The server stores these keys and the results of the operations. Subsequent requests with the same key return the stored result without re-executing the operation.
2. Resource Versioning: In update operations, using versioning can ensure idempotency. Clients include the resource version in their requests, and the server only applies changes if the version matches the current state.
3. Conditional Requests: HTTP provides mechanisms like If-Match and If-None-Match headers to make requests conditional. This can help ensure that operations are applied only when certain conditions are met, thus maintaining idempotency.
4. State Checks: Before performing an operation, the system can check the current state to determine if the operation has already been applied. This is common in systems where the state can be queried efficiently.
Idempotency in Functional Programming
In functional programming, idempotency is often associated with pure functions. A pure function, by definition, does not produce side effects and always returns the same result given the same input. While not all pure functions are idempotent, idempotency is a valuable property in the context of functional programming because it ensures predictability and reliability.
For example, consider a function that sanitizes input strings by removing whitespace:
haskell
Copy code
sanitize :: String -> String
sanitize = trim . replaceMultipleSpaces
-- Assuming 'trim' and 'replaceMultipleSpaces' are both idempotent functions
If both trim and replaceMultipleSpaces are idempotent, then sanitize is also idempotent. Applying sanitize multiple times to the same input string yields the same result as applying it once.
Challenges and Considerations
While idempotency offers numerous benefits, implementing it can be challenging. Some operations are inherently non-idempotent, such as generating unique identifiers or processing user input that changes with each request. In such cases, ensuring idempotency requires careful design and often involves trade-offs.
Moreover, idempotency can have performance implications. For example, maintaining idempotency keys or resource versions might require additional storage and processing overhead. Balancing these costs with the benefits of idempotency is a critical consideration in system design.
Conclusion
Idempotency is a fundamental concept that enhances the reliability, safety, and simplicity of computing systems. By ensuring that operations can be repeated without unintended consequences, idempotency plays a crucial role in the robustness of web services, the consistency of databases, and the predictability of functional programming. Understanding and implementing idempotency effectively can significantly improve system design and operation, making it an indispensable tool in the arsenal of software engineers and computer scientists.

1. Relational Model: The foundation of an RDBMS is based on the relational model, which organizes data into tables (relations) consisting of rows (tuples) and columns (attributes). Each table represents an entity, and each row represents a unique record of that entity.
2. Tables: Tables are structured with predefined columns that define the attributes or properties of the entities they represent. For example, a "Customers" table might have columns like CustomerID, Name, Address, etc.
3. Rows: Each row in a table represents a specific instance of the entity being modeled. For instance, in a "Customers" table, each row would represent a unique customer.
4. Columns: Columns define the type of data that can be stored in them (such as integers, strings, dates, etc.) and enforce constraints (like uniqueness or not null) to maintain data integrity.
5. Keys: Keys are used to uniquely identify rows within a table. The Primary Key uniquely identifies each record in the table, while a Foreign Key establishes a link between tables, ensuring referential integrity.
6. Relationships: Relationships between tables are established using keys. A common relationship is the One-to-Many relationship, where one record in one table can relate to many records in another table.
7. Normalization: This process eliminates redundancy and ensures data integrity by organizing data into tables and defining relationships between them. It reduces data duplication and improves efficiency.
8. ACID Properties: Transactions in RDBMS systems are designed to be reliable and consistent, adhering to the ACID properties:
- Atomicity: Transactions are treated as a single unit of work.
- Consistency: Data must meet all defined rules (constraints) before being committed.
- Isolation: Transactions occur independently without interference.
- Durability: Changes made by committed transactions are permanent and survive system failures.
9. SQL (Structured Query Language): SQL is the standard language used to interact with RDBMS. It provides commands for querying data, updating records, defining schemas, and managing permissions.
10. Transactions: A transaction is a sequence of SQL operations that are treated as a single unit. Transactions ensure data consistency and integrity by either committing (making changes permanent) or rolling back (reverting changes) based on success or failure.
These concepts form the backbone of RDBMS systems, providing a robust framework for storing, manipulating, and retrieving data in a structured manner.

Starting from the... | 0 | 2024-06-26T10:43:29 | https://dev.to/novita_ai/all-you-need-to-know-about-the-limitations-of-large-language-models-220i | llm | ## Introduction
What are the limitations of large language models (LLMs)? Starting from the definition of LLM, we are going to discuss 8 limitations one by one. For each limitation, we ask 3 questions: What does this limitation mean and why? What are the implications of this limitation in practice? How to deal with this limitation. If you want to get a deeper understanding of LLMs to better interact with them, keep reading!
## What Are Large Language Models?
Large Language Models (LLMs) represent a significant leap forward in artificial intelligence, particularly in natural language processing (NLP). These sophisticated algorithms are designed to comprehend and generate human language, mimicking human-like understanding and expression. Operating within the realm of deep learning, LLMs employ neural networks with numerous layers to process extensive textual data, learning intricate patterns and relationships embedded in language.
Neural networks, fundamental to LLMs, operate as interconnected layers of neurons that sequentially process input data to produce meaningful outputs. Each layer performs specialized computations: lower layers capture basic patterns, while higher layers integrate these patterns into more complex linguistic structures such as grammar rules and semantic meanings. This hierarchical learning process empowers LLMs to achieve high accuracy in tasks ranging from text generation to sentiment analysis and beyond.
In recent years, LLM development has shifted towards Transformer-based architectures. More and more popular LLMs, e.g. LLaMA 3 8B and 70B, are being integrated into [API](https://novita.ai/llm-api), enabling users to conveniently and efficiently leverage the power of different LLMs.
## Limitation 1: LLMs Can't Process Everything At Once
### What Does This Mean And Why?
LLMs can't process everything at once due to their architecture and computational constraints. LLMs are trained on vast amounts of data to understand and generate human-like text. However, due to hardware limitations and the need to maintain efficiency, they are designed to handle a fixed number of tokens (a basic unit of text, which can be a word, a character, or even a subword, depending on the model's design.). This constraint ensures that the model operates within a manageable memory footprint and processing time.
### What Are the Implications in Practice?
Essentially, attempting to paste a lengthy article or multi-page document into an LLM prompt will typically result in an error message indicating that the maximum token limit has been exceeded.
### How to Deal with It in Practice?
1. Input Chunking: Break down large inputs into smaller, manageable chunks that fit within the token limit.
2. Summarization: Before processing, summarize lengthy texts to capture the essence in a concise form.
3. Prioritization: Determine the most critical information to include in the input to maximize the utility of the model's response.
4. Iterative Interaction: Engage in a step-by-step dialogue with the LLM, where each response is used to inform the next input.
5. Model Selection: Choose an LLM that best fits the needs of your task in terms of token capacity and other performance metrics.
## Limitation 2: LLMs Don't Retain Information Between Interactions
### What Does This Mean And Why?
It means that these models do not have a persistent memory that spans across different sessions or queries. Each time an LLM processes a request, it treats it as an isolated instance without any recollection of previous exchanges. This is a fundamental aspect of how LLMs operate and is primarily due to their stateless nature.
The reason behind this is rooted in the design and training of LLMs. They are typically trained on large datasets to develop a statistical understanding of language patterns. However, they are not designed to maintain a continuous state or context across different inputs. This design choice is partly due to the complexity of implementing and managing stateful interactions at scale and partly to ensure privacy and avoid the potential misuse of retained personal data.
### What Are the Implications in Practice?
The lack of retained information between interactions has several practical implications:
1. Context Loss: LLMs may not recognize or remember the context from previous conversations, which can lead to responses that seem out of context or repetitive.
2. User Experience: Users may need to provide background information repeatedly, which can be frustrating and inefficient.
3. Complex Task Handling: Tasks that require understanding or building upon previous interactions, such as multi-step problem-solving or ongoing narratives, can be challenging for LLMs.
4. Data Privacy: On a positive note, this limitation helps protect user privacy by ensuring that personal data is not stored or linked across sessions.
### How to Deal with It in Practice?
1. Explicit Context: Always provide necessary context within each interaction to ensure the LLM can generate an appropriate response.
2. Structured Inputs: Use structured formats for inputs that clearly delineate the task and any relevant information.
3. Session Management: If using an LLM in an application, implement session management on the application level to track context and state.
4. Iterative Dialogue: Design interactions in a way that each step builds upon the previous one, with the understanding that the LLM itself does not remember past interactions.
5. Feedback Loops: Use feedback mechanisms to refine and improve the model's responses over time, even though it does not remember individual interactions.
## Limitation 3: LLMs Can't Update Their Knowledgebase in Real-Time
### What Does This Mean And Why?
The statement that Large Language Models (LLMs) can't update their knowledge base in real-time refers to the fact that these models are trained on static datasets and do not have the capability to incorporate new information as it becomes available. This means that once an LLM is trained, its understanding of the world is frozen at the time of its last training cycle.
The reason for this limitation is twofold. Firstly, the training process for LLMs is resource-intensive and time-consuming, involving massive datasets and significant computational power. Secondly, there's a need for stability in the model's performance; constant updates could lead to inconsistencies and a lack of reliability in the model's outputs.
### What Are the Implications in Practice?
The inability of LLMs to update their knowledge base in real-time has several implications:
1. Stale Information: LLMs may provide outdated or irrelevant information if the query relates to recent events or developments that occurred after the model's last training.
2. Lack of Relevance: In fast-moving fields such as technology, finance, or current events, LLMs might not be able to provide the most up-to-date insights or data.
3. Dependency on External Updates: Users may need to rely on other sources or supplementary systems to ensure the information provided by LLMs is current.
### How to Deal with It in Practice?
1. Hybrid Systems: Combine LLMs with other systems that can provide real-time data or updates, such as APIs that fetch the latest information from reliable sources.
2. Filtering and Verification: Implement mechanisms to filter out or flag information that may be outdated and encourage users to seek verification from current sources.
3. Continuous Monitoring: Keep an eye on the development of new technologies and methodologies that might allow for more dynamic and real-time knowledge updates in LLMs.
## Limitation 4: LLMs Can Sometimes Say Things That Don't Make Sense
### What Does This Mean And Why?
It means that despite their advanced capabilities, they can occasionally generate responses that are illogical, nonsensical, or irrelevant to the query. This can happen for several reasons:
1. Lack of Complete Understanding: LLMs generate text based on patterns in the data they were trained on, but they do not fully understand the meaning or context of the language they produce.
2. Ambiguity in Input: If the input to the LLM is ambiguous or poorly formulated, the model may struggle to generate a coherent response.
3. Overfitting to Training Data: LLMs might generate responses that are overly literal or repetitive, based on the patterns they've seen in their training data, without considering the nuances of real-world language use.
4. Randomness in Generation: LLMs incorporate a degree of randomness in their text generation process, which can sometimes lead to nonsensical outputs.
### What Are the Implications in Practice?
1. Reliability Issues: Users may not trust the LLM's outputs if they encounter nonsensical responses, which can affect the model's credibility.
2. Miscommunication: In critical applications, such as customer service or information provision, nonsensical responses can lead to confusion or incorrect actions.
3. User Frustration: Repeated encounters with nonsensical outputs can lead to user frustration and a negative perception of the technology.
### How to Deal with It in Practice?
1. Input Refinement: Ensure that the inputs to the LLM are clear, concise, and well-structured to minimize ambiguity.
2. Post-Processing: Implement post-processing steps to check the coherence and relevance of the LLM's outputs before they are presented to the user.
3. Feedback Mechanisms: Allow users to provide feedback on the quality of the responses, which can be used to improve the model over time.
4. Model Fine-Tuning: Fine-tune the LLM on domain-specific data to improve its understanding and reduce the likelihood of nonsensical outputs.
## Limitation 5: LLMs Don't Understand Subtext
### What Does This Mean And Why?
When we say that Large Language Models (LLMs) don't understand subtext, we're referring to their inability to grasp the implied, indirect, or underlying meaning of language that goes beyond the literal interpretation of words. This is due to several reasons:
1. Lack of Contextual Awareness: LLMs primarily rely on patterns in the data they've been trained on and may not have the capacity to infer the subtleties of human communication.
2. Absence of Emotional Intelligence: They lack the emotional intelligence to understand the emotions and intentions behind the words.
3. Literal Interpretation: LLMs tend to interpret text in a literal sense, which can lead to misunderstandings when the text contains sarcasm, irony, or other forms of subtext.
### What Are the Implications in Practice?
1. Miscommunication: There's a risk of miscommunication, especially in nuanced or sensitive conversations where the subtext is critical.
2. Limited Creativity: LLMs may struggle to generate creative or nuanced content that relies on subtext for impact.
3. Inability to Detect Sarcasm or Jokes: They may take sarcastic or humorous remarks literally, leading to inappropriate responses.
### How to Deal with It in Practice?
1. Clear and Direct Communication: Encourage users to communicate in a clear and direct manner to minimize the risk of misinterpretation.
2. Training on Nuanced Language: If possible, train the LLM on datasets that include examples of subtext to improve its recognition capabilities.
3. Human Oversight: Implement a system where human operators can step in when the conversation becomes nuanced or sensitive.
## Limitation 6: LLMs Don't Really Understand Reasoning
### What Does This Mean And Why?
LLMs don't actually understand cause and effect in the world. Sometimes they give answers about causes and effects that seem right, but they don't truly grasp the underlying reasons why those cause-and-effect relationships exist.
The key idea is that when these models handle causality correctly, it's not because they've learned the causal mechanisms from data. Instead, it's because the texts they trained on contained representations that explicitly stated causal links between concepts. So the models have just memorized those stated relationships, not actually discovered the causal patterns in data on their own. They're just very good "parrots" when it comes to reciting causal facts stated in their training data (Zečević et al., 2023).
### What Are the Implications in Practice?
This raises serious issues for using these models in important real-world applications that require robust causal reasoning - things like automated decision-making systems, planning tools, or medical diagnostic assistants. Since they lack a true grasp of underlying causes, they are prone to repeating biases and inconsistencies present in their training data.
What's more, it will likely be extremely difficult to get these "causal parrot" language models to transfer their apparent skill at causal reasoning to completely new subject areas.
### How to Deal with It in Practice?
1. Manage expectations: Recognize the limitations of LLMs as "causal parrots" and don't treat their outputs as if they demonstrate deep causal reasoning. Communicate clearly that their responses are based on statistical patterns in data, not an innate understanding of cause and effect.
2. Use LLM outputs as supportive tools, not final decisions: Treat LLM generations as useful starting points or supportive evidence, but have human experts critically evaluate them and make final judgments, especially for high-stakes decisions requiring causal reasoning.
3. Focus on narrow, data-rich domains: LLMs may exhibit more reliable "causal parrot" abilities in specialized areas where vast amounts of curated data encoding causal knowledge already exists.
4. Pursue hybrid approaches: Combine LLM output with other AI components that can provide deeper causal modeling, such as constraint-based or neural causal models learned from interventional data.
5. Don't overclaim: Be very cautious about claiming an LLM exhibits general causal reasoning abilities based on narrow benchmarks which may just reflect quirks in its training data.
## Limitation 7: LLMs Can Perpetuate Biases and Stereotypes
### What Does This Mean And Why?
It means that they may reflect and reinforce the prejudices, biases, or stereotypes present in the data they were trained on. This happens because:
- Data Representation: If the training data contains biased language or examples, the LLM will likely learn and reproduce these biases.
- Lack of Diverse Perspectives: Insufficient representation of diverse perspectives in the training data can lead to a narrow and potentially biased worldview.
- Unconscious Bias: The creators of the training data and the model itself may have unconscious biases that are inadvertently encoded into the model's responses.
### What Are the Implications in Practice?
1. Unfair Representation: Certain groups or individuals may be misrepresented or marginalized due to the biases in the model's responses.
2. Ethical Concerns: There are ethical implications regarding fairness, equality, and the potential for harm caused by biased outputs.
3. Legal and Compliance Risks: Biased outputs can lead to legal issues, especially in sectors bound by anti-discrimination laws.
4. Public Trust: The credibility and trustworthiness of the technology may be undermined if it is perceived as biased.
### How to Deal with It in Practice?
1. Diverse Training Data: Ensure that the training data is diverse and representative of various cultures, genders, ages, and social backgrounds.
2. Bias Detection and Mitigation: Implement algorithms and processes to detect and mitigate biases in the training data and model outputs.
3. Regular Audits: Conduct regular audits of the model's outputs to identify and correct any emerging biases.
4. Transparency: Be transparent about the model's limitations and potential biases with users and stakeholders.
## Limitation 8: LLMs May Violate Privacy
### What Does This Mean And Why?
The potential for Large Language Models (LLMs) to violate privacy refers to their capability to infer and disclose personal information from text inputs, which can lead to privacy breaches. This is significant because LLMs, with their advanced inference capabilities, can analyze unstructured text and deduce sensitive personal attributes such as location, income, and sex with high accuracy (Staab et al., 2023).
The reason this happens is due to the models' extensive training on diverse datasets, which enables them to recognize patterns and make predictions based on subtle cues in the text. Moreover, the proliferation of LLMs in various applications, such as chatbots, increases the risk of privacy invasion through seemingly innocuous interactions.
### What Are the Implications in Practice?
1. Increased Surveillance: There's a risk of heightened surveillance, as personal data can be inferred and potentially misused by entities with malicious intent.
2. Data Breaches: Privacy violations can lead to data breaches, exposing individuals to identity theft and other cybercrimes.
3. Trust Erosion: The erosion of trust in digital platforms and services that utilize LLMs, as users may fear their personal information is not secure.
4. Legal and Compliance Issues: Organizations may face legal challenges and penalties for non-compliance with data protection regulations such as GDPR.
### How to Deal with It in Practice?
1. Enhanced Anonymization Techniques: Developing and implementing more robust text anonymization methods to protect personal data from inference.
2. Improved Model Alignment: Aligning LLMs to prevent them from generating or inferring privacy-sensitive information, focusing on ethical guidelines and privacy-preserving outputs.
3. Regulatory Oversight: Strengthening regulations to govern the use of LLMs and ensuring that they are designed with privacy by design.
4. Transparent AI Practices: Promoting transparency in AI practices, including how data is used and protected.
5. Technical Innovations: Exploring new technologies and methodologies that enhance privacy, such as differential privacy and federated learning.
6. Ethical AI Development: Encouraging the development of LLMs with a strong ethical framework that prioritizes user privacy and data security.
## Conclusion
Have you grasped all the limitations we have discussed? Here's a summary of LLMs' limitations for you:
**1. LLMs can't process everything at once
2. LLMs don't retain information between interactions
3. LLMs can't update their knowledgebase in real-time

_"Why aren't I working for myself?"_
I mean, think about it. No boss telling you what to do, no deadlines, _**no annoying co-workers**_, sounds like a dream. **You** decide when you log on and off, **you** decide what you work on, and **you** set your deadlines.
#What is a SaaS Startup?
Naturally, I turned to SaaS, the latest hot topic in the world of software development. I'm sure most people know what it is, or at least have heard of it. Love it or not, it's one of the easiest ways to profit from programming, next to freelancing.
For those who have been living under a rock for the past couple of years, a SaaS Startup is a company that offers software as a service, paid for by end users usually in a subscription model. They're usually developed by individuals or small teams, giving them the potential for large revenue margins. They often focus on delivering a solution to a specific audience's issues, while building a loyal customer base simultaneously.
But I'll save the specifics of starting a SaaS Startup for another article. Instead, today I want to focus on the very first step for any SaaS Startup.
#So what do I build?
You've decided to launch your own SaaS Startup, planning to build the next Instagram. So you open up your favourite code editor (Dark mode, hopefully) run `npm create next app` and...
_"Wait, where do I start?"_
We've all been there, motivated to begin programming, but then overwhelmed by the blank file. This is precisely the reason why it is crucial to _know_ what you're going to build _before_ you build it.
"But where do you find SaaS ideas? They don't just grow on trees, Josh". Correct! But the main issue with this question is it ignores the premise of a SaaS Startup. The market for startups is extremely oversaturated, so you need to make sure yours stands out. It can't just _'exist'_, it needs to solve something. The best startups succeed because they solve something most people experience, but are too lazy to solve.
The key to finding a SaaS idea is to look at other's pain. People are only going to pay for something that brings value to them, so you need to provide them with that value before they'll hand over their bank details.
Even if you don't find anything good, start creating something. Make a fun little game, write a blog post like this one, build a note-taking app. There will be issues along the way that you'll encounter, and boom, there's your SaaS Startup
Stop thinking, start doing.

1,883,766 | Mastering Dependency Injection: Enhancing Code Modularity and Maintainability | As the sun set behind the rolling hills of Silicon Valley, John found himself at a crucial... | 0 | 2024-06-26T10:42:26 | https://dev.to/luisfpedroso/mastering-dependency-injection-enhancing-code-modularity-and-maintainability-m6g | designpatterns, softwareengineering, programming, javascript | As the sun set behind the rolling hills of Silicon Valley, John found himself at a crucial crossroads. Months ago, a library was introduced into the project, only to now reveal numerous bugs, leaving John with the daunting task of updating 30 files to achieve the team's goal. Faced with this challenge, John realized that simply updating imports and refactoring the code wasn't the best path forward. Instead, he saw an opportunity to apply a design pattern that would not only resolve the current issue but also streamline future modifications.
John decided to use Dependency Injection (DI), a powerful design pattern that decouples the code, shifting responsibilities outside of a single file. This approach ensures that individual files don't directly consume third-party packages but rely on functions or classes within the project. By doing so, John could transform a potentially extensive refactor into a single, manageable transformation down the road.
In this post, we’ll explore how to implement Dependency Injection by creating an API client that consumes data from the GitHub API, demonstrating the pattern's practical application and benefits.
### The first class:
Let's start by creating our first class, which we'll call `Api`.
```ts
class Api {
constructor() {}
async get(url: string) {
}
}
export default Api;
```
This class has a single method called get, responsible for executing `GET` requests. Now, think for a minute about how you would implement the code for this method. Would you add a library such as Axios and call it in the `get` method? Something like:
```ts
async get(url: string) {
const response = await axios.get(url)
return response.data
}
```
If you thought about doing something like this, let me tell you that here's our core for dependency injection. Instead of attaching this class with a third-party library, we will move the dependency one level up. Therefore, all the logic regarding the headers of the request, or how to perform a request, will be placed in a new class responsible for only this.
To achieve that, let's create a new field for our class called `client`, and set its value in the constructor of the class.
```ts
class Api {
private client: Fetcher<any>;
constructor(client: Fetcher<any>) {
this.client = client
}
}
```
or, to simplify:
```ts
class Api {
constructor(private client: Fetcher<any>) {}
}
```
And update our `get` method:
```ts
async get(url: string) {
return this.client.get(url);
}
```
### The contract
Now, we need to create something called `Fetcher`. What is Fetcher? It’s an interface that defines methods for those that implement it. By doing this, we can ensure that the `Api` class will call a valid method in the `get` method.
Let's create it:
```ts
interface Fetcher<T> {
initialize(baseUrl: string): void;
get(url: string): Promise<T>;
}
export default Fetcher;
```
In this interface, we define two functions, `initialize`, and `get`. You will understand the purpose of the initialize in a bit.
### The first fetcher
It's time to create the first class responsible for making requests.
<img src="https://i.giphy.com/media/v1.Y2lkPTc5MGI3NjExMTdxZ3UxZjJ2Y2tobzlyZG01dm5uOWsxbHRncHNqNzllNDVmdmVjYyZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/1QlEEZdYLwIwV0f8AL/giphy.gif" />
Let's call it `FetchFetcher`.
```ts
import Fetcher from "./Fetcher";
class FetchFetcher<T> implements Fetcher<T> {
private baseUrl: string = "";
initialize(baseURL: string): void {
this.baseUrl = baseURL;
}
async get(url: string): Promise<T> {
const response = await fetch(`${this.baseUrl}${url}`);
const parsedResponse = await response.json();
return parsedResponse;
}
}
export default FetchFetcher;
```
Beautiful, huh? Now we have a class that uses the Javascript Fetch API and does a single stuff.
### Connecting the pieces
To connect everything, let's create an initialization file:
```ts
import Api from "./Api";
import FetchFetcher from "./FetchFetcher";
async function main() {
const fetchFetcher = new FetchFetcher();
fetchFetcher.initialize("https://api.github.com");
const api = new Api(fetchFetcher);
const response = await api.get("/users/luisfilipepedroso");
console.log(response);
}
main();
```
You might be asking yourself, why create a class called `Api` to perform requests, or wouldn't it be better to call `get` from the FetchFetcher directly? Well, you are half right, since, at this moment, we can create any fetchers we want. Take a look:
```ts
import axios, { AxiosInstance } from "axios";
import Fetcher from "./Fetcher";
class AxiosFetcher<T> implements Fetcher<T> {
private axiosInstance: AxiosInstance | null = null;
initialize(baseURL: string): void {
this.axiosInstance = axios.create({
baseURL,
});
}
async get(url: string): Promise<T> {
const response = await this.axiosInstance!.get<T>(url);
return response.data;
}
}
export default AxiosFetcher;
```
Now we have a class that uses the Axios library, and we can initiate it in the main file:
```ts
import Api from "./Api";
import AxiosFetcher from "./AxiosFetcher";
import FetchFetcher from "./FetchFetcher";
async function main() {
const axiosFetcher = new AxiosFetcher();
// const fetchFetcher = new FetchFetcher();
axiosFetcher.initialize("https://api.github.com");
// fetchFetcher.initialize("https://api.github.com");
const api = new Api(axiosFetcher);
const response = await api.get("/users/luisfilipepedroso");
console.log(response);
}
main();
```
And the code will continue working, without touching the `Api` class.

### Conclusion
Using Dependency Injection allows us to decouple our code, making it more flexible and easier to maintain. By abstracting the HTTP client, we can swap implementations without modifying the core logic.
To recap, here are the key benefits and steps we covered:
- **Decoupling Code**: Dependency Injection helps to separate concerns by shifting dependencies outside of a single class.
- **Flexibility**: We can easily switch between different HTTP clients (like Fetch and Axios) without altering the core Api class.
- **Maintainability**: This approach makes the codebase more maintainable by isolating third-party dependencies.

In this tutorial we will create a rest api using TypeScript. We will use OOP approach to create the api.
### Why Object-Oriented Programming (OOP) approach?
- OOP allows you to create reusable code that is easy to maintain and extend.
- OOP provides a clear and organized structure for your code.
- OOP promotes code reusability and modularity.
- OOP makes it easier to manage complex systems by breaking them down into smaller, more manageable pieces.
### Prerequisites
- Node.js
- TypeScript
- Express.js
- MongoDB
### Step 1: Check if Node.js is installed
Open your terminal and type the following command:
```bash
node -v
```
If Node.js is installed, you will see the version number. If not, you can download it from [here](https://nodejs.org/en/download/).
### Step 2: Check if TypeScript is installed
Open your terminal and type the following command:
```bash
tsc -v
```
If TypeScript is installed, you will see the version number. If not, you can install it by running the following command:
```bash
npm install -g typescript
```
### Step 3: Create a Node.js project
Create a new directory for your project and navigate to it:
```bash
mkdir oop-rest-api
cd oop-rest-api
```
### Step 4: Initialize the project
Run the following command to initialize the project:
```bash
npm init -y
```
### Step 5: Install the required packages
```bash
npm install express mongoose cors helmet dotenv
npm install --save-dev typescript @types/node @types/express @types/mongoose @types/cors @types/helmet
```
### Step 6: Create a tsconfig.json file
```bash
tsc --init
```
### Step 7: Create a src directory and other required directories
```bash
mkdir src src/controllers src/models src/routes src/services src/helpers src/config src/interfaces src/repository
```
### Step 8: Create a user model
Create a new file in the src/models directory called user.model.ts and add the following code:
```typescript
import mongoose from "mongoose";
import IUser from "../interfaces/IUser";
const userSchema = new mongoose.Schema(
{
name: { type: String, required: true },
email: { type: String, required: true },
password: { type: String, required: true },
},
{
timestamps: true,
}
);
const User = mongoose.model<IUser>("User", userSchema);
export default User;
```
### Step 9: Create an interface for the user model
Create a new file in the src/interfaces directory called user.interface.ts and add the following code:
```typescript
import mongoose from "mongoose";
interface IUser extends mongoose.Document {
id: number;
name: string;
email: string;
password: string;
}
export default IUser;
```
#### Step 10: Create a Base Repository
```typescript
export interface BaseRepository<T> {
create(data: T): Promise<T>;
findAll(): Promise<T[]>;
findById(id: string): Promise<T | null>;
update(id: string, data: T): Promise<T | null>;
delete(id: string): Promise<T | null>;
findAllPaginatedWithFilter(
filter: any,
page: number,
limit: number
): Promise<T[]>;
}
```
#### Step 11: Create a Database Connection
Create a new file in the src/config directory called db.ts and add the following code:
```typescript
import mongoose from "mongoose";
class Database {
private readonly URI: string;
constructor() {
this.URI =
process.env.MONGO_URI || "mongodb://localhost:27017/express-mongo";
this.connect();
}
private async connect() {
try {
await mongoose.connect(this.URI);
console.log("Database connected successfully");
} catch (error) {
console.error("Database connection failed");
}
}
}
export default Database;
```
### Step 12: Create a user repository generic class and implement the base repository
Create a new file in the src/repository directory called generic.repository.ts and add the following code:
```typescript
import { BaseRepository } from "../interfaces/base.repository";
import mongoose from "mongoose";
class GenericRepository<T extends mongoose.Document>
implements BaseRepository<T>
{
private readonly model: mongoose.Model<T>;
constructor(model: mongoose.Model<T>) {
this.model = model;
}
async create(data: T): Promise<T> {
return this.model.create(data);
}
async findAll(): Promise<T[]> {
return this.model.find().exec();
}
async findById(id: string): Promise<T | null> {
return this.model.findById(id).exec();
}
async update(id: string, data: T): Promise<T | null> {
return this.model.findByIdAndUpdate(id, data, { new: true }).exec();
}
async delete(id: string): Promise<T | null> {
return this.model.findByIdAndDelete(id).exec();
}
async findAllPaginatedWithFilter(
filter: any,
page: number,
limit: number
): Promise<T[]> {
return this.model
.find(filter)
.skip((page - 1) * limit)
.limit(limit)
.exec();
}
}
```
### Step 13: Create a user repository
Create a new file in the src/repository directory called user.repository.ts and add the following code:
```typescript
import IUser from "../interfaces/IUser";
import User from "../models/user.model";
import GenericRepository from "./generic.repository";
class UserRepository extends GenericRepository<IUser> {
constructor() {
super(User);
}
// create custom methods for user repository
async findByEmail(email: string): Promise<IUser | null> {
return User.findOne({ email });
}
async findByName(name: string): Promise<IUser | null> {
return User.findOne({ name });
}
}
export default UserRepository;
```
### Step 14: Create a user service
Create a new file in the src/services directory called user.service.ts and add the following code:
```typescript
import IUser from "../interfaces/IUser";
import UserRepository from "../repository/user.repository";
class UserService {
private readonly userRepository: UserRepository;
constructor() {
this.userRepository = new UserRepository();
}
async create(data: IUser): Promise<IUser> {
return this.userRepository.create(data);
}
async findAll(): Promise<IUser[]> {
return this.userRepository.findAll();
}
async findById(id: string): Promise<IUser | null> {
return this.userRepository.findById(id);
}
async update(id: string, data: IUser): Promise<IUser | null> {
return this.userRepository.update(id, data);
}
async delete(id: string): Promise<IUser | null> {
return this.userRepository.delete(id);
}
async findByEmail(email: string): Promise<IUser | null> {
return this.userRepository.findByEmail(email);
}
async findByName(name: string): Promise<IUser | null> {
return this.userRepository.findByName(name);
}
}
export default UserService;
```
### Step 15: Create a user controller
Create a new file in the src/controllers directory called user.controller.ts and add the following code:
```typescript
import { Request, Response } from "express";
import IUser from "../interfaces/IUser";
import UserService from "../services/user.service";
class UserController {
private readonly userService: UserService;
constructor() {
this.userService = new UserService();
}
async create(req: Request, res: Response) {
try {
const data: IUser = req.body;
const user = await this.userService.create(data);
res.status(201).json(user);
} catch (error: unknown) {
throw new Error(error as string);
}
}
async findAll(req: Request, res: Response) {
try {
const users = await this.userService.findAll();
res.status(200).json(users);
} catch (error) {
throw new Error(error as string);
}
}
}
export default UserController;
```
### Step 16: Create a user route
Create a new file in the src/routes directory called user.route.ts and add the following code:
```typescript
import { Router } from "express";
import UserController from "../controllers/user.controller";
class UserRoute {
private readonly userController: UserController;
public readonly router: Router;
constructor() {
this.userController = new UserController();
this.router = Router();
this.initRoutes();
}
private initRoutes() {
this.router.post("/", this.userController.create.bind(this.userController));
this.router.get("/", this.userController.findAll.bind(this.userController));
}
}
export default new UserRoute().router;
```
### Step 17: Create global error handler middleware
Create a new file in the src/helpers directory called error-handler.ts and add the following code:
```typescript
import { Request, Response, NextFunction } from "express";
// write a single class for 404 and 500 error
import { Request, Response, NextFunction } from "express";
class ErrorHandler {
static notFound(req: Request, res: Response, next: NextFunction) {
res.status(404).json({ message: "Resource not found" });
}
static serverError(
error: Error,
req: Request,
res: Response,
next: NextFunction
) {
res.status(500).json({ message: error.message });
}
}
export default ErrorHandler;
```
### Step 18: Create an App class
Create a new file in the src directory called app.ts and add the following code:
```typescript
import express, { Application } from "express";
import cors from "cors";
import helmet from "helmet";
import ErrorHandler from "./helpers/error-handler";
import Database from "./config/config";
import dotenv from "dotenv";
import UserRoute from "./routes/user.routes";
import userRoutes from "./routes/user.routes";
class App {
private readonly app: Application;
private readonly port: number;
constructor() {
this.app = express();
this.port = parseInt(process.env.PORT || "3000");
this.init();
}
private init() {
this.initConfig();
this.initMiddlewares();
this.initRoutes();
this.initErrorHandling();
}
private initConfig() {
new Database();
}
private initMiddlewares() {
this.app.use(cors());
this.app.use(helmet());
this.app.use(express.json());
this.app.use(express.urlencoded({ extended: true }));
dotenv.config();
}
private initRoutes() {
this.app.use("/api/v1/users", userRoutes);
}
private initErrorHandling() {
this.app.use(ErrorHandler.notFound);
this.app.use(ErrorHandler.serverError);
}
public listen() {
this.app.listen(this.port, () => {
console.log(`Server is running on http://localhost:${this.port}`);
});
}
}
export default App;
```
### Step 19: Create an index file
Create a new file in the src directory called index.ts and add the following code:
```typescript
import App from "./app";
const app = new App();
app.listen();
```
### Step 20: Write your scripts in package.json
```json
"scripts": {
"start": "node dist/index.js",
"dev": "nodemon src/index.ts",
"build": "tsc",
"test": "echo \"Error: no test specified\" && exit 1"
}
```
### Step 21: Run the application
```bash
npm run dev
```
### Step 22: Test the application
Create a test.http file in the root directory and add the following code:
```http
### 404 Not Found
GET http://localhost:3000/api/v1/userspost
```
```
### Create a new user
POST http://localhost:3000/api/v1/users
Content-Type: application/json
{
"name": "John Doe",
"email": "luli@yopmail.com",
"password": "password"
}
```
```
### Get all users
GET http://localhost:3000/api/v1/users
```
### Conclusion
We have successfully created a rest api using TypeScript and OOP approach. Feel free to expand on this project by adding more features and functionalities like authentication, authorization, error responses, validation, etc.

It is maintained by Facebook and a community of individual developers and companies. React allows developers to create large web applications that can update and render efficiently in response to data changes.
Here are some key points about React:
**1.Component-Based Architecture:** React encourages the development of UI components, which can be reused and nested within other components. This modular approach promotes code reusability and makes maintenance easier.
**2.Virtual DOM:** React uses a virtual DOM, a lightweight copy of the actual DOM. When the state of an object changes, React updates the virtual DOM first, then efficiently updates the real DOM to match. This improves performance and user experience.
**
3.JSX Syntax:** React uses JSX, a syntax extension that allows writing HTML-like code within JavaScript. This makes it easier to visualize the structure of the UI components and blend JavaScript logic with UI definitions.
**
4.Unidirectional Data Flow:** React enforces a unidirectional data flow, meaning data is passed from parent to child components via props. This makes it easier to debug and understand the flow of data within the application.
**5.State Management:** React provides a way to manage state within components, enabling dynamic and interactive user experiences. For more complex state management, libraries like Redux or Context API are often used in conjunction.
**6.React Hooks:** Introduced in React 16.8, hooks are functions that let developers use state and other React features without writing a class. Common hooks include useState for state management and useEffect for side effects.
**7.Ecosystem: **React has a rich ecosystem of libraries and tools that support development, such as React Router for navigation, Redux for state management, and Next.js for server-side rendering.
**8.Community and Support:** React has a large, active community and a wealth of resources including documentation, tutorials, and third-party libraries, making it a reliable choice for web development. React.js is widely used in modern web development due to its flexibility, performance, and strong community support. It powers the front ends of many well-known applications and websites, making it a valuable skill for web developers. | nagabhushan_adiga_a383471 |

1,901,152 | StringBuilder | C# | *Salom barchaga! Bugun biz C# dastulash tilida StringBuilder sinfini ko'rib chiqamiz! * Reja: Sal... | 0 | 2024-06-26T10:37:21 | https://dev.to/ozodbek_soft/stringbuilder-c-4paf | dotnet, csharp, uzbek, stringbuilder | **Salom barchaga! Bugun biz C# dastulash tilida StringBuilder sinfini ko'rib chiqamiz! **
**Reja:**
- Sal kam hech qanday reja yo'q, Sababi biz bugungi darsda StringBuilderni chunchaki dialog sifatida 0 dan Prof darajagacha o'rganamiz! O'ylaymanki bu sizga va boshqalarga yoqadi. Eslatib o'tamiz ushbu maqolada men `sb` o'zgaruvchi nomini e'lon qilmasdan ishlatishim mumkin, lekin chalgimaslik uchun uni shunday tasavvur qiling
```StringBuilder sb = new StringBuilder(); // oddiy o'zgaruvchi nomi```
**1 Savol:** StringBuilder nima va Nimaga kerak o'zi ?
_C# dasturlash tilida StringBuilder bu - Stringlarni manipulation qilish, ya'ni boshqarish. StringBuilderni ishlatishdan maqsad, bir necha o'zgarishlar kiritilishi mumkin bo'lgan stringlarni ishlashini samaraliroq qilishdir, Ya'ni biz "Hello" so'zini yoki boshqa bir so'zni, gaplarni teskari tartibda chiqaruvchi dastur tuzmoqchi bo'lsak. Ko'pincha tajribasizlik qilib stringni o'zini ishlatamiz, Lekin bu juda katta xato.
Misol: Agar string ishlatsak, String bu immutable hisoblanadi, O'zgarmas._
Buni Amaliy qilib ko'rsatsak!
```
string say = "Hello";
string natija = "";
for (int i = say.Length - 1; i >= 0; i--)
natija += say[i];
Console.WriteLine(natija); // olleH
```
_Ushbu holatda "Hello" Length 5 ga teng bo'lganligi sabab, Processor tomonida 5 marta yangi str ochiladi. yani bu 5 ta operatsiya bajaradi degani. Har for aylanganda bittadan yangi o'zgaruvchi yaratilib oxiri shu teskari chiqaradi. Bu endi biz kutgan natijani chiqargani bilan, optimal usul emas. Optimal usul qanday bo'ladi desangiz pastga qarang 👇_
```
using System.Text;
string say = "hello";
StringBuilder natija = new StringBuilder();
for (int i = say.Length - 1; i >= 0; i--)
natija.Append(say[i]);
Console.WriteLine(natija); // olleh
```
Bunisi ancha yaxshi variantde 😄
Chunki StringBuilder bitta stringni o'zgartiradi. Stringni o'zi esa qayta qayta yangi string yarataveradi.
**2 savol: ** - StringBuilder Classini qanday yaratishimiz mumkin ?
Xuddi pastdagidey 👇
```
using System.Text;
StringBuilder salom = new StringBuilder();
```
_Aytgancha ushbu classni yaratishda doim `new` kalit so'zi ishlatiladi!
Tushunganetion ?
_
**3 - savol:** StringBuilder ga matn, string qo'shish uchun qanday usullar yoki functionlar bor ?
_Quyidagicha 👇_
```
StringBuilder salom = new StringBuilder();
salom.Append("alik");
salom.Append("yaxshi");
```
Append(); methodi orqali qo'sha olamiz!
Tushundilami ?
**4 - savol: ** StringBuilderdagi mavjud stringni qanday qilib o'zgartirishimiz mumkin ?
```
salom.Replace("salom", "alik");
```
Replace(); methodi eng qulay methodlardan biri. Yani bu yerda birinchi parametr bo'lmish "salom" ni "alik" ga almashtirdik
**5 - savol: ** StringBuilderdagi ma'lum bir indexdagi methodni olish yoki o'zgaritish qilish uchun qaysi usullar bor ?
Buning javobi oddiy insert() va remove(), To'gri shu yerda aqliy savol kelishi mumkin. Ularni farqi nimada ?
`Insert()` - bu StringBuilderni ma'lum bir matniga yana matn yoki belgilar qo'shish uchun. Ya'ni 3 qatordan boshlab "ozod" matnini qo'sh degandek :)
`Remove()` - ushbu method, StringBuilderdagi matnning ma'lum bir joyidan boshlab, ma'lum bir ta belgi o'chiradi. Yani 4 chi belgidan boshlab 2 ta belgini o'chir degandek!
Insert(); ga misol:
```
StringBuilder nnnn = new StringBuilder("Salom");
nnnn.Insert(6, "O'zbeklar"); // Salom O'zbeklar
```
Remove(); ga misol:
```
StringBuilder sb = new StringBuilder("Hello Uzbeks");
sb.Remove(5, 3); // Hellobeks
```
Tushundilarmi endi ?
**6 savol: ** StringBuilderning uzunligini qanday aniqlashimiz mumkin ?
Javobi oddiy: Length methodi orqali, lekin shu o'rinda Lengthni olish uchun bitta int o'zgaruvchisi kerak bo'lishi mumkin. Pastdagiga qarangda👇
```
StringBuilder sb = new StringBuilder("Hello");
int sbUzunligi = sb.Length; // 5
```
**7 savol: ** StringBuilder obyektini stringga o'girish uchun nima qilamiz?
Ushbu amalni bajarishimiz uchun bizga ToString() methodi yordamga keladi. Uni ishlashi oddiy >> Amaliy ko'rishingiz mumkin 👇
```
string natija sb = ToString();
```
**8 Savol: **StringBuilderning si'gimi va uni qanday o'zgartiramiz ?
`Sig'im is Capasity` degan
**Javob: **StringniBuilderning sig'imi degani, u uning ichki xotiradagi maksimal uzunligi. Sigimi oshib ketganda xotiradan yangi joy ajratiladi. Sigimni Capacity methodi orqali ko'rishimiz va o'zgartirishimiz mumkin 👇
```
int sigim = sb.Capacity;
sb.Capacity = 100; // sigimi 100 ta belgi uchun bo'ladi endi😄
```
**9 savol: **StringBuilderdan nega foydalanish kerak ? Afzalliklar nima uni ?
- Tezroq ishlayd, anu stringga o'xshab yangi obyektlar yaratib o'tirmaydi.
- Xotira samaradorligini oshiradi | chunki 👆
- Bir necha o'zgarishlar kerak bo'lganda, qulaylikni dodasini yaratadi.
**10 savol: ** StringBuilderni qachon ishlatmaslik kerak?
_StringBuilderni kichik stringlar qo'shish, yoki kichik o'zgartirishlar uchun ishlatmaslik kerak. Yani kichik narsa, amaliyotlarda stringni o'zi ham yetadi. Lekin kattaroq narsaga esa StringBuilderni ishlatishimiz kerak . Agar katta narsalarda ham StringBuilder ishlatishni xohlamasangiz unda tabriklayman siz yaxshi dasturchi emassiz (Hazil albatta)._
**Oxirida bir Yetim Savolcha bo'lishi mumkin 😄: StringBuilder so'zini ma'nosi nima ? **

Buyers often... | 0 | 2024-06-26T10:23:54 | https://dev.to/robert_hagemann_dff52cbfd/enhancing-real-estate-listings-with-virtual-home-staging-308j | In the competitive world of real estate, making a lasting first impression is crucial. Buyers often decide within moments whether a property is worth their time and investment. As technology continues to revolutionize various industries, real estate has not been left behind. One of the most innovative advancements is [virtual home staging](https://www.bellastaging.ca/)—a powerful tool that can transform the way properties are marketed and perceived.
**What is Virtual Home Staging?
**Virtual home staging involves using digital tools to furnish and decorate a property virtually. Unlike traditional home staging, which requires physical furniture and decor, virtual staging utilizes software to add stylish furnishings, decor, and even improvements to the photos of empty or sparsely furnished homes. This technology allows real estate agents and homeowners to present properties in their best light, attracting more potential buyers.
**Benefits of Virtual Home Staging
**Cost-Effective: Traditional home staging can be expensive, involving rental fees for furniture, decor, and labor costs for staging professionals. Virtual staging, on the other hand, is significantly more affordable, as it eliminates the need for physical items and logistics.
**Flexibility:** With virtual staging, there are endless possibilities for design. Different styles and themes can be applied to suit various target audiences, whether it's a modern, minimalist look or a cozy, traditional ambiance. This flexibility allows for customization that can appeal to a wider range of buyers.
**Time-Saving:** Physical staging can take days or even weeks to arrange. Virtual staging can be completed in a matter of hours, speeding up the listing process and allowing properties to hit the market faster.
**Enhanced Visual Appeal:** High-quality, digitally staged photos can make a property stand out in online listings. A visually appealing presentation can attract more views and generate greater interest, potentially leading to quicker sales and higher offers.
**Showcasing Potential:** Virtual staging helps buyers visualize the full potential of a space. Empty rooms can appear smaller and less inviting, while a virtually staged room can show its true potential, making it easier for buyers to imagine themselves living there.
**How Does Virtual Home Staging Work?**
The process of virtual home staging typically involves the following steps:
**Photography:** High-resolution photos of the empty or sparsely furnished property are taken. Good lighting and angles are crucial to ensure the best possible base images.
**Design Selection:** Based on the target audience and market trends, appropriate furnishings and decor styles are selected. This could range from contemporary to classic, ensuring the property appeals to its intended buyers.
**Digital Staging:** Professional designers use specialized software to add the chosen furniture and decor to the photos. They ensure that the staging looks realistic and aligns with the proportions and dimensions of the actual space.
**Final Touches:** Any necessary adjustments are made to enhance the overall look and feel of the staged images. This may include tweaking lighting, adding small decor items, or making minor digital repairs to the property.
**Marketing:** The final staged images are then used in online listings, brochures, and other marketing materials to attract potential buyers.
**Best Practices for Virtual Home Staging**
Keep it Realistic: While it's tempting to create a perfect, magazine-worthy look, it's essential to keep the staging realistic. Overly exaggerated or impractical designs can mislead buyers and cause disappointment during in-person viewings.
**Highlight Key Features:** Use staging to draw attention to the property's best features, such as large windows, architectural details, or spacious layouts. Effective staging can help emphasize these selling points.
**Stay Neutral**: To appeal to the broadest audience, it's best to use neutral colors and styles. Bold or unique designs can be polarizing and may not resonate with all potential buyers.
**Work with Professionals:** Hiring experienced virtual staging professionals ensures high-quality results. They have the skills and knowledge to create visually appealing and realistic staged images.

1,901,142 | Learn How to Use Postman for Sending POST Requests | Understanding how to send a POST request in Postman is a crucial skill for any developer or tester.... | 0 | 2024-06-26T10:23:34 | https://dev.to/satokenta/learn-how-to-use-postman-for-sending-post-requests-4hff | postman | Understanding how to send a POST request in Postman is a crucial skill for any developer or tester. POST requests are typically used for submitting data to a server, such as creating new resources or uploading files.
## What is a POST Request?
A POST request is an HTTP request method used for sending data to a target server. In RESTful APIs, POST requests are commonly employed to create new resources. Unlike GET requests, POST requests include a request body that contains the data submitted by the client.
## Prerequisites
Before you begin, ensure you have completed the following preparations:
1. **Install Postman**: Download and install the software from the [Postman](https://apidog.com/blog/beginners-postman-tutorial/) website.
2. **Available API Endpoint**: Find an API endpoint that accepts POST requests. You can use public APIs such as JSONPlaceholder or a self-hosted test server.
## Steps to Send a POST Request in Postman
### Step 1: Create a New Request
Open Postman and click the **“New”** button at the top left, then choose **“Request”** to create a new request.
### Step 2: Name the Request and Select a Collection
In the dialog box that appears, name your request and choose a collection to save it in. If you don’t have a collection, you can create a new one.
### Step 3: Set the Request Method and URL
1. At the top of the request editor is a dropdown menu. By default, it shows **“GET”** . Click the dropdown menu and select **“POST”** .
2. In the text box to the right of the dropdown menu, enter the target URL.
### Step 4: Add the Request Body
Click the **“Body”** tab, where you'll see several options. Select **“raw”** and ensure the dropdown menu to the right shows `JSON`. Then, enter the data you want to send into the text box.
### Step 5: Send the Request
Once all configurations are done, click the **“Send”** button at the top right. Postman will then send this POST request to the target server.
### Step 6: Review the Response
At the bottom of the Postman window, you will see the server's response. The response includes the status code (such as `201 Created`), response headers, and the response body. Parsing this information will help you confirm whether the request was successful and understand the data returned by the server.
### Additional Considerations
1. **Verify Data Format**: Ensure the data sent complies with the format required by the API documentation. For example, in JSON format, make sure all key-value pairs are correct.
2. **Error Handling**: If the request fails, check the status code and message in the response. For instance, a `400 Bad Request` status code indicates that something is wrong with the request, making it unprocessable by the server.
3. **Security**: In real environments, avoid sending sensitive data over unencrypted connections (use HTTPS over HTTP). Additionally, for APIs requiring authentication, ensure authentication headers are correctly set.
## Alternative Tools
Compared to Postman, [Apidog](https://www.apidog.com/?utm_source=&utm_medium=blogger&utm_campaign=test1) stands out as a compelling solution for handling dynamic values and automatically generating JSON bodies. Apidog offers several noteworthy features, including time-saving automatic JSON body generation, which eliminates the need for manual work required to write requests. Users can choose from various predefined templates, streamlining the process and ensuring consistent JSON structures across different requests. Those interested should give it a try.
### Effortless JSON Body Generation:
Apidog's automatic JSON body generation is a time-saving feature that eliminates the need for manual work required to write requests. Users can choose from various predefined templates, streamlining the process and ensuring consistent JSON structures across different requests.
## Conclusion
In this tutorial, we learned how to send a simple POST request using Postman. Whether you're involved in front-end development, back-end development, or API testing, mastering this skill is extremely important. Utilize the powerful tool Postman to boost your efficiency and achieve your tasks more effectively.
Postman dramatically simplifies API testing and debugging, enhancing development efficiency. We hope this article helps you gain a more comprehensive understanding of and leverage Postman for sending POST requests, making your development process a more enjoyable journey. | satokenta |

1,901,130 | Adding search to a static Astro website | Why add a search page? I always like it when a website includes a search page, it makes it... | 0 | 2024-06-26T10:18:02 | https://www.thomasledoux.be/blog/search-static-astro-website | astro, webdev, javascript, programming | ## Why add a search page?
I always like it when a website includes a search page, it makes it easy to find the relevant content you're looking for.
This is especially useful when your website starts growing, and you've written a whole bunch of blog posts for example (it's me 😅).
At my agency job I create websites for large corporations with large budgets, and we usually go for Algolia there, since it's quite easy to use and it has some out of the box React components etc.
But Algolia gets quite pricy quite fast, so I wanted to look into something self hosted for my website.
I looked into what the Astro team is doing on their Starlight website, and found out they use [Pagefind](https://pagefind.app), "A fully static search library that aims to perform well on large sites, while using as little of your users’ bandwidth as possible, and without hosting any infrastructure".
Sounds good to me, let's start using it!
## Setting up the Astro integration
This part is **very** easy.
First we install `astro-pagefind` and `pagefind`
```bash
npm install astro-pagefind pagefind
```
Then we include it into our Astro config
```ts
import pagefind from "astro-pagefind";
import { defineConfig } from "astro/config";
export default defineConfig({
integrations: [pagefind()],
});
```
Make sure to att the `pagefind` integration as the last element in the index, to make sure it runs **after** the other integrations.
By adding the integration, Pagefind will run as the last part of your build process, and index all the content from your static output.
You'll see something like this at the end of the build process:
```
Running Pagefind v1.1.0 (Extended)
Running from: "/Users/thomasledoux/Documents/website-thomas-astro"
Source: ".vercel/output/static"
Output: ".vercel/output/static/pagefind"
[Walking source directory]
Found 58 files matching **/*.{html}
[Parsing files]
Did not find a data-pagefind-body element on the site.
↳ Indexing all <body> elements on the site.
1 page found without an <html> element.
Pages without an outer <html> element will not be processed by default.
If adding this element is not possible, use the root selector config to target a different root element.

[Building search indexes]
Total:
Indexed 1 language
Indexed 56 pages
Indexed 3345 words
Indexed 0 filters
Indexed 0 sorts
Finished in 0.197 seconds
```
## Creating the search UI
For the search UI I opted to create a separate search page for now, mainly because I didn't want to bother with modals for the search etc.
Pagefind provides default CSS and JS for the search element, so you can get up and running in minutes.
So I created a page under `pages/search.astro`
```astro
---
import Layout from "~/layouts/Layout.astro";
---
<Layout>
<link href="/pagefind/pagefind-ui.css" rel="stylesheet" />
<script is:inline src="/pagefind/pagefind-ui.js"></script>
<div id="search"></div>
<script>
// @ts-expect-error
import { PagefindUI } from "@pagefind/default-ui";
window.addEventListener("DOMContentLoaded", () => {
new PagefindUI({
element: "#search",
showSubResults: true,
autofocus: true,
});
const el = document.querySelector(".pagefind-ui");
const input = el?.querySelector<HTMLInputElement>(`input[type="text"]`);
const clearButton = el?.querySelector(".pagefind-ui__search-clear");
// Check if the current URL has any query params
const url = new URL(window.location.href);
const params = new URLSearchParams(url.search);
const query = params.get("q");
// If query exists on page load
if (query && input) {
input.value = query;
input.dispatchEvent(new Event("input", { bubbles: true }));
}
input?.addEventListener("input", (e) => {
const input = e.target as HTMLInputElement;
const url = new URL(window.location.href);
const params = new URLSearchParams(url.search);
params.set("q", input.value);
window.history.replaceState({}, "", `${url.pathname}?${params}`);
});
clearButton?.addEventListener("click", () => {
const url = new URL(window.location.href);
const params = new URLSearchParams(url.search);
params.delete("q");
window.history.replaceState({}, "", `${url.pathname}`);
});
});
</script>
</Layout>
```
As you can see, just calling the `new PagefindUI()` constructor with the correct element referenced is all you need to do to get the basics done.
The only extra code I added is code to handle query params, both reading from the query params and inputting that into the search element on page load and writing to the query params when searching.
I also added a click listener on the default `clear` button which pops up the moment you entered something into the search input, just to make sure the query params are also cleared.
The result after executing a search will look like this:
You get things like syntax highlighting, image detection and subsections for your headings out of the box!
## Configuring the indexing
After executing a search on the keyword `remix`, which I use on my website a few times, I noticed that some results were being returned that I did not expect to be returned.
I saw all my automatically generated [tag pages](https://www.thomasledoux.be/blog/auto-tag-pages-astro-mdx) were being returned as results for this search term.
This was caused by my tags section at the top of the page, which always includes all the tags used on my blog.
So I should somehow make sure this content does not get indexed.
Luckily Pagefind provides something for this out of the box, you can use the `data-pagefind-ignore="all"` attribute on the HTML tag which you don't want to have indexed. It will also ignore all the children underneath it.
With this set up, I now have a simple search purely based on my static content, no need to set up a SaaS product for this and completely free!
## Conclusion
For a website with almost completely static content like mine, Pagefind was the ideal solution to integrate search into my website. The fact that it's free, and doesn't require setting up a complex indexing mechanism is great.
This blog post was inspired by Alex Trost's [blog post](https://trost.codes/posts/adding-simple-search-to-an-astro-blog/).
Want to see it in action? Find it on [my site](https://thomasledoux.be/search).
The diff of the code I needed to add for this can be found on [my GitHub](https://github.com/thomasledoux1/website-thomas-astro/pull/22/files)

1,901,125 | Verifying Column Types in Your Database Schema | Ensuring consistency in your database schema is crucial for maintaining data integrity and... | 0 | 2024-06-26T10:08:14 | https://dev.to/msnmongare/verifying-column-types-in-your-database-schema-jlb | sql, postgres, tutorial, beginners | Ensuring consistency in your database schema is crucial for maintaining data integrity and facilitating efficient database operations. One important aspect of schema consistency is verifying the column types across your tables. This is especially important when working with large databases or integrating new data sources. In PostgreSQL, you can use the `information_schema.columns` view to easily check the data types of columns in a specific table.
### Step-by-Step Guide to Verifying Column Types
#### 1. Understanding the Information Schema
The information schema in PostgreSQL is a set of views that provide metadata about the database objects, including tables, columns, and their data types. The `information_schema.columns` view contains detailed information about every column in the database, making it an ideal resource for verifying column types.
#### 2. Crafting the SQL Query
To verify the column types of a specific table, such as `constituencies`, you can use the following SQL query:
```sql
SELECT column_name, data_type
FROM information_schema.columns
WHERE table_name = 'constituencies';
```
Here's what the query does:
- **FROM information_schema.columns**: It queries the `columns` view from the `information_schema`.
- **WHERE table_name = 'constituencies'**: This condition filters the results to include only the columns from the table named `constituencies`.
- **SELECT column_name, data_type**: It selects the column names and their respective data types.
#### 3. Running the Query
You can execute this query in any PostgreSQL client or tool you use to interact with your database. For example, in `psql` (PostgreSQL’s command-line interface), you would connect to your database and run the query as follows:
Then, paste and execute the SQL query:
```sql
SELECT column_name, data_type
FROM information_schema.columns
WHERE table_name = 'constituencies';
```
#### 4. Interpreting the Results
The query will return a list of columns and their data types for the `constituencies` table. Here’s a sample output:
| column_name | data_type |
|-----------------|-------------------|
| id | integer |
| name | character varying |
| population | integer |
| area | double precision |
In this example:
- The `id` column is of type `integer`.
- The `name` column is of type `character varying` (or `varchar`).
- The `population` column is of type `integer`.
- The `area` column is of type `double precision`.
#### 5. Ensuring Consistency
By verifying the column types, you can ensure that the data types are consistent with your database design and application requirements. Inconsistencies in data types can lead to errors, inefficient queries, and data integrity issues. Regularly checking and maintaining consistent data types helps in:
- **Data Integrity**: Preventing data type mismatches and ensuring accurate data storage.
- **Performance Optimization**: Ensuring that queries run efficiently by using appropriate data types.
- **Simplified Maintenance**: Making it easier to manage and update the schema without unexpected issues.
### Conclusion
Verifying column types in your PostgreSQL database schema is a vital step in maintaining consistency and ensuring the smooth operation of your database. By leveraging the `information_schema.columns` view, you can quickly and effectively check the data types of columns in your tables. Regularly performing these checks will help you maintain a robust and reliable database schema, ultimately supporting the integrity and performance of your applications. | msnmongare |
